KyCalc Scientific Vector Calculator V2.07
1.0 Introduction to the KyCalc Scientific Calculator
1.1 Introduction
The KyCalc Scientific Vector Calculator is a calculator that can be
used by anyone for virtually any application. Whether you do extensive
number-crunching or just want to balance your checkbook you'll find the
KyCalc calculator easy to use and packed with features to fit your
particular needs.
1.2 Overview
The KyCalc calculator is designed around the end user - you. If you
are already familiar with the operation of a pocket calculator you will
feel right at home with the way the KyCalc calculator looks and
operates. It can be loaded memory resident with the full keyboard
display or with just the number display showing ("windowed") so you can
see the screen. Or it can be loaded non-resident. When it is loaded
memory resident you can call up the calculator at anytime in the middle
of any other program, perform you calculations, and then return to the
program you were in right where you left off. When you do exit you
have the option of having the answer you arrived at typed into whatever
program you are in as if you had typed it from the keyboard yourself!
All commonly used functions are activated by single keystrokes using
the lettered keys that normally lay under your left hand while typing.
This leaves the right hand free to remain over the keypad where you can
enter in numbers even if you don't have the "Num Lock" light.
All common calculator functions are supported: addition, subtraction,
multiplication, division, square, square-root, inverse, percentage,
constant, memory add, and memory exchange.
Also included are some features found in only a few calculators: fixed
floating decimal point for those of us that don't like hitting the
decimal point when entering dollars and cents, and an X : Y exchange
for when you enter in 23 divided by 276 when you really wanted 276
divided by 23.
The features that make it a scientific calculator are: scientific
notation display and entry, sines, cosines, tangents, natural and base
ten logarithms, power calculations, factorials, and Bessel functions of
the first and second kind. The trigometric functions can be used in
1
KyCalc Scientific Vector Calculator V2.07
degrees, radians, or gradients.
Parenthetic operation is also supported so that calculating
5sin(6*(25+19)) is a breeze.
Two dimensional vector arithmetic is also supported with the vectors
entered and displayed in either a+jb format or in polar notation.
Vector arithmetic includes: addition, subtraction, division,
multiplication, inverse, powers, and roots.
1.3 Hardware Requirements
The KyCalc Scientific Vector Calculator is designed to work with the
IBM PC, XT, AT, and most IBM-Compatible computers with either color or
monochrome displays, 256K of memory, and running with DOS 2.0 or
higher. Once loaded the KyCalc calculator uses 75K of memory. Note
that the KyCalc calculator is very "well-behaved" and can therefore be
loaded either before or after other memory resident programs like
Sidekick and Superkey. If you find a program that is not compatible
with the KyCalc calculator please let us know.

KyCalc Scientific Vector Calculator V2.07
2.0 Overall Operation
2.1 Getting Started with the KyCalc Calculator
There are three options available for loading the KyCalc calculator:
non-resident, resident, and resident initially windowed.
If you want to load the program for immediate use and don't want it to
take up system memory the it should be loaded non-resident. This is
done by entering in at a DOS command prompt:
> kycalc /n
and the calculator full keyboard display will appear with the
calculator read for use.
To load the KyCalc calculator for later using in another program
(memory residant) us the /r option:
> kycalc /r
and the program type out:
┌───────────────────────────────────────────┐
│ KyCalc Scientific Vector Calculator V2.07 │
│ (C) KyCorp Information Group, Inc. 1987 │
└───────────────────────────────────────────┘
To call up press Ctrl - Alt - K
from that point on to call up the KyCalc calculator hold down both the
Control and Alt key, then at the same time press the "K" key from
whatever program you are in and the KyCalc calculator will appear.
Ensure the KyCalc calculator is loaded before operating system programs
like Gem Desktop and Microsoft Windows.
Note that the KyCalc calculator cannot be called up if the display
screen is in a graphics mode.
To load KyCalc memory resident but have it initially in the "windowed"
mode (see section 3.2 for a detailed discussion of "windowed") us the
/w option:
> kycalc /w
For the examples in the rest of the manual it will be assumed that you
3
KyCalc Scientific Vector Calculator V2.07
have loaded the KyCalc calculator using the /r option.
2.2 Entering Numbers
Numbers can be entered into the calculator by either using the number
keypad or the numbers on the top row of the keyboard. If you make a
mistake while entering a number, hit the backspace key a few times to
erase the digits. Type in:
123456789
In the display window you will see:
╔═════════════════════════════════════╗
║ 1 2 3 4 5 6 7 8 9 ║
╚═════════════════════════════════════╝
Now hit the backspace key twice:
┌────┐ ┌────┐
│ <- │ │ <- │
└────┘ └────┘
And you will see:
╔═════════════════════════════════════╗
║ 1 2 3 4 5 6 7 ║
╚═════════════════════════════════════╝
Some people find the double spaced display hard to read. In order to
have the display single spaced press the "O" key and you will see:
╔═════════════════════════════════════╗
║ 1234567 ║
╚═════════════════════════════════════╝
To go back to double spaced press the "O" key again.
2.3 Leaving the KyCalc Calculator
You can leave the KyCalc calculator by holding down the Alt key and
pressing the "X" key. This will put you back into the program you
called the calculator from.
You also have the option of having the display typed into the program
you called the calculator from. This feature is very useful when doing
4
KyCalc Scientific Vector Calculator V2.07
work with a program requiring number entries or if you are just using a
word processor.
To show you how this works, call up your favorite word processor and
type in "This number came from my calculator: ". Now press the Ctrl-
Alt-K key combination to call up the KyCalc calculator. Notice that
the number in the display is just as you left it. Now hold down the
Ctrl key and press the "X" key. This will put you back into you word
processor and will also type out the number that was in the display.
You should see in your word processor:
This number came from my calculator: 1234567
Regardless of whether you are in single spaced display or double spaced
the number typed into your program on leaving the calculator will be
single spaced.
2.4 Sample Calculations
Let's try a simple division calculation. Call up the KyCalc calculator
again (Ctrl-Alt-K). You should still see in you display:
╔═════════════════════════════════════╗
║ 1 2 3 4 5 6 7 ║
╚═════════════════════════════════════╝
Now press the space bar and you should see the division box light up
(turn yellow on a color system). To perform a division calculation you
can either hit the space bar or press the "/" key. If you use the
space bar the right hand can stay over the keypad and the left hand
over the function keys. Now enter in the number "7" and you will see:
╔═════════════════════════════════════╗
║ 7 ║
╚═════════════════════════════════════╝
Now press the "Enter" key. This has the same effect as hitting the "="
key, however the enter key is easier to hit. You should see in you
display:
╔═════════════════════════════════════╗
║ 1 7 6 3 6 6 . 7 1 4 2 8 5 7 1 4 3 ║
╚═════════════════════════════════════╝
Let's try that again. Enter in:
1234567 / 7 =
5
KyCalc Scientific Vector Calculator V2.07
Again you should see:
╔═════════════════════════════════════╗
║ 1 7 6 3 6 6 . 7 1 4 2 8 5 7 1 4 3 ║
╚═════════════════════════════════════╝
Note that 16 digits are displayed. The accuracy of this calculator is
limited to the first 15 digits.
Let's try to get our original number back. Enter in:
* 7 =
The "*" means "times" in computer jargon so that you don't confuse it
with the letter "x". For multiplication you can either hit the gray
key with the "*" over by the keypad or press shift-8 the enter the "*"
located there.
The original display should be back:
╔═════════════════════════════════════╗
║ 1 2 3 4 5 6 7 ║
╚═════════════════════════════════════╝
2.5 Error Messages
Whenever you try to perform an operation which is not mathematically
valid or goes beyond the capabilities of the calculator an error
message will be displayed. Enter in:
/ 0 =
What you should see is:
╔═════════════════════════════════════╗
║ Division by Zero Error ║
╚═════════════════════════════════════╝
To clear the error message press the "Esc" key. Whenever an error
message is displayed the only key which will operate is the "Esc" key.
2.6 Precedence and Parenthesis
Precedence refers to the order in which functions are executed. On the
KyCalc calculator the Bessel function has the lowest precedence, then
comes addition and subtraction, then multiplication and division, then
powers, and finally the functions that are acted on immediately: sine,
cosine, tangent, 1/x, logs, squares, square-roots, and factorials.
6
KyCalc Scientific Vector Calculator V2.07
Let's take a look at the equation 6 + 5 * 2. If this were entered in
on a simple four function calculator the answer would come out to be 22
since it would first calculate 6 + 5 and then multiply by 2. For most
scientific applications it is preferable to perform multiplications and
divisions before additions and subtractions. The KyCalc calculator
treats the above equation like this: 6 + (5 * 2). Let's try it. Enter
in:
6 + 5 * 2 =
And you should see:
╔═════════════════════════════════════╗
║ 1 6 ║
╚═════════════════════════════════════╝
Notice that as soon as you hit the "*" that a "+" appeared next to
"Pending:". This is because the addition is a pending operation. The
KyCalc calculator is holding off on the addition until the addition
function has precedence over the next operation. The KyCalc calculator
has room for up to 20 pending operations.
It is not always desireable to have the multiplication performed before
addition. To override the precedence of a particular function you can
use parenthesis. Try entering the equation:
(6 + 5) * (2 + 4) =
This comes out to 66. Notice that when you hit the "(" that it will
light up in the status box located in the upper left-hand corner of the
screen. Instead of using the "(" located above the "9" key you may
also use the "[", whichever you prefer.

Execute key: Q
Inverse function: Turns off inverse/second
Precedence: Immediate
Vector Operations Permitted: N/A
Pending Notation: N/A
To execute a primary function labeled in the upper left-hand corner of
a box on the KyCalc calculator you just press the associated key. For
example, to square the number in the display press the key "E" on the
keyboard. In order to execute the secondary function labeled in the
upper right-hand corner of a box, such as the square-root function or
an arcsine, you first press the letter "Q" and then the function key.
For example, to get the square-root of a number in the display press
"Q" and then "E". To get the arcsine of a number in the display press
"Q" then "S".
To cancel the Inverse press "Q" a second time.
Errors: None

The "windowed" display is used in order to see the display screen that
the KyCalc calculator was called up from. To revert back to the normal
full screen display press the "W" key again.
To move the window around hold down a shift key and press the arrows.
Holding down the shift key and pressing Home, PgUp, End, or PgDn will
place the window in one of the four corners of the screen.
Errors: None

┌───────┐
3.3 Square / Square-Root │x² √x│
│ E │
└───────┘
Execute key: E
Inverse function: square-root
Precedence: Immediate
Vector operation: Yes
Pending Notation: N/A
The square function takes the display and multiplies it times itself.
For example, 3 squared equals 3 * 3 which equals 9. For vector
operations 2 + j4 squared equals:
(2 + j4)(2 + j4) = 2*2 + 2*j4 + 2*j4 + j4*j4
= 4 + j8 + j8 + -16
= 4 + j16 - 16
= -12 + j16
The square-root finds a number which multiplied by itself will equal
the number in the display. For example the square-root of 9 equals 3
since 3*3 = 9. For vector operations the square-root of -12 + j16
equals 2 +j4 since (2 + j4)(2 + j4) = -12 + j16.
Errors: The KyCalc calculator can only handle numbers up to
1.797+308, therefor squaring a number with an exponent > 154
will result in a "Floating Point Processor Error".
Attempting to take the square-root of a negative number will
result in a "Error - Square Root of a Neg. Number" error
display.

┌───────┐
3.4 Powers / Factorial │xⁿ x!│
│ R │
└───────┘
Execute keys: R, ^ (Power), or ! (Factorial)
Inverse function: Factorial
Precedence: 2 (Power), Immediate (Factorial)
Vector Operations Permitted: Power only
Pending Notation: ^ (Power)
Power operations raise a number to a specific power. 3 raised to the
power of 2 equals 9 (3 ^ 2 = 9). To take the root of a number raise it
to 1/root. For example 9 ^ (1/2) = 9 ^ 0.5 = 3. Raising a number to a
negative number is the same as raising it to a positive number except
the answer is inverted. For example 3 ^ -2 = 1/9 = 0.111111111111.
The same operations apply to vectors. For example:
(-12 + j16) ^ -(1/2) = [(2 + j4)(2 + j4)] ^ -(1/2)
= [1 / (2 + j4)(2 + j4)] ^ (1/2)
= 1 / (2 + j4)
= [1 / (2 + j4)] * [(1 - j2)(1 - j2)]
= (1 - j2) / (2*1 + j4*1 - j2*2 - j2*j4)
= (1 - j2) / (2 + j4 - j4 + 8)
= (1 - j2) / 10
= 0.1 - j0.2
Factorials may be calculated for integers from 0 to 170. Numbers are
rounded off to the lower integer value. For example:
6.9! = 6! = 6*5*4*3*2*1 = 720.
Errors: Raising a negative number to a non-integer power or raising
zero to a negative power will result in a "Error - Arguments
in Invalid Domain" error display.
Attempting to raise a number to a vector results in a "Error
- Exponent Must Be a Scaler" error display.
Taking the factorial of a negative number will result in a
"Domain Error - Negative Factorial" error display.
Taking the factorial of a number greater than 170 will result
in a "Factorial Out of Range - Limit 170" error display.

3.5 1/x / Percent │1/x %│
│ T │
└───────┘
Execute keys: T, % (Percent)
Inverse function: Percent
Precedence: Immediate
Vector Operations Permitted: 1/x only
Pending Notation: N/A
The 1/x function calculates 1 divided by the display.
The percent function if used without any pending operation (i.e. not in
the middle of an addition, subtraction, etc.) then the number is
divided by 100. If there is a pending operation then a percentage of
the pending number is calculated. For example, enter in:
25 + 5% =
When the "%" key is pressed 5% of 25 is calculated (1.25). When the
"=" key is pressed 1.25 is added to 25 (26.25).
Errors: 1/0 results in a "Division by Zero" error display.

Pressing the "Y" key enters in the number PI. PI = 3.14159265359
Pressing the "K" key just prior to pressing the "=" key saves the
operation as a constant for future use. Subsequent pressing of the "="
key performs the same operation. For example, enter in:
25 * 5k =
This results in the number 125 being displayed. Note that after the
"=" is pressed that the "*" is still pending. Pressing the "=" key
again will multiply the number by 5 again (625). Now enter in:
35 =
Since a constant operation is still pending then 35 * 5 is calculated
(175).
Errors: None.

Pending Notation: N/A
The number in the display is assumed to be in the units specified in
the status box. For example, if you press the "S" key with the number
30 in the display and the "deg" highlighted in the status box then the
calculator will calculate the sine of 30 degrees (0.5). If the "rad"
were selected then the calculator would calculate the sine of 30
radians (-0.98803162409).
For the inverse functions the result is calculated and displayed in the
units specified in the status box. For example if degrees were
selected then the arcsine of 0.5 would be 30 degrees.
To calculate a complex trigometric function utilize the parenthesis
prior to executing the sine. For example, to calculate 5 * sin (30/6)
enter in:
5 * (30 / 6) S =
The result is 0.43577871374 if set to degrees. When the ")" key is
pressed the number in the display is the calculation 30 / 6 which
equals 5. Pressing the "S" key calculate the Sin (5).
Errors: Tangents of 90 degrees, PI/2 radians, or 100 gradients
results in a "Infinity Error - Undefined Tangent" error
display.
Arcsines or arccosines > 1 result in a "Invalid Argument
