- Purpose
- ~~~~~~~
- # ("octothorp", "number sign", or "hash", whichever you prefer)
- is a infix command-line calculator. Features include
- factorials, defined constant „ (pi), scientific notation
- (floating point), hex, decimal, octal, binary input and output
- representations, radian or degree representations of angles,
- bitwise operators, and integer-specific functions mod and div.
-
-
- Why did we write this?
- ~~~~~~~~~~~~~~~~~~~~~~
- We found other calculators (TSRs, 4dos' %@eval[]) to be
- inadequate and/or cumbersome in many situations. As a result,
- we decided to write one for ourselves. Originally it only had
- support for expressions and bitwise operators, but features were
- added to make it more versatile and easy to use.
-
-
- Usage
- ~~~~~
- Typing "#" and pressing Enter at the command line will result in
- the following screen:
-
-
- # Version 1.00· Copyright 1991 by Amit K. Mathur and Peter Harwood.
-
- Usage: # </outputparameters> <expression to evaluate>
- Where the expression can contain any of the following:
- '+', '-', '*', '/', '^', and '!' operators
- brackets, nested as deep as you want
- 'e' to specify scientific notation
- 'pi', specifically 3.14159265358979
- the trig functions 'sin', 'cos', 'tan', and 'atan'
- the logarithmic functions 'exp' and 'ln'
- 'sqrt' as an alternative to numeric^0.5
- the Integer only functions 'div' and 'mod'
- the bitwise operators 'not', 'and', 'shl', 'shr',
- 'xor', and 'or'
- you can prefix a number with an '$','%','O', or 'D' to
- specify hex, binary, octal or degrees respectively
-
- Output Parameters are 'b' for binary, 'h' for hex,
- 'd' for decimal, 'o' for octal or any combination.
-
- # can handle values from 3.4e-4932 to 1.1e4932
-
-
- An arithmetic expression typed after the "#" (and a space!) will
- be evaluated and output.
-
- Ex #1. Typing "# 3+4(9)" and pressing Enter will result in the
- following:
-
- # Version 1.00· Copyright 1991 by Amit K. Mathur and Peter Harwood.
- Math Co-processor Detected and Utilized.
-
- 3+4(9)= 39
-
- Note in this case the lack of the "*" to indicate
- multiplication. It is actually optional in this case. Note
- also that on a computer with no math co-processor, a message of
- "No Math Co-Processor Found, Emulation Used." will instead
- result.
-
- Ex #2. Typing "# /bo %011011011 shl 2 xor ($34 and (o707773645 div
- 3))" will result in the following:
-
- # Version 1.00· Copyright 1991 by Amit K. Mathur and Peter Harwood.
- Math Co-processor Detected and Utilized.
-
- %011011011shl2xor($34and(o707773645div3))= 1530 in octal
- %011011011shl2xor($34and(o707773645div3))= 1101011000 in binary
-
- The "/bo" indicates your wish to see binary and octal
- representations of the answer. The spaces within the expression
- are filtered out by the parser.
-
- Ex #3. Typing "# sin(d90)*4!+exp(2)^sqrt(2*tan(pi/4))" will yield:
-
- # Version 1.00· Copyright 1991 by Amit K. Mathur and Peter Harwood.
- Math Co-processor Detected and Utilized.
-
- sin(d90)*4!+exp(2)^sqrt(2*tan(pi/4))= 40.9188286785579
-
- The "d" in "sin(d90)" indicates that the number following the
- "d" is in degrees. (It is converted to radians)
-
-
- Notes
- ~~~~~
- Brackets can virtually be nested as deeply as you want,
- considering that you will hit the DOS command-line limit before
- you can blow our stack.
-
- In 4dos, users will realize that the carat ("^") is used to
- separate commands. This conflicts with our exponent function.
- One way around it is to use the 4dos escape character. This
- character is by default Control-X (""). Type this character
- before the carat and 4dos will ignore the command separator.
- Another way is to redefine the command separator to something
- else in your 4dos.ini file (or with SETDOS).
-
- Another conflict with 4dos is the percent character ("%") used
- to indicate binary numbers. 4dos tries
-
- Make sure when using the different output formats to put your
- parameters BEFORE the expression. If you do not, # will think
- it is part of the expression! Also remember that multiple
- output parameters must be grouped together after the "/", eg.
- "/bdh" for binary, decimal, and hex output.
-
- We decided not to write in support for floating point using
- other bases than ten (decimal). First of all, there's no real
- reason for it, and second, we couldn't get it working quite
- correctly due to floating point errors in base conversion.
-
- Things like "# and" will work. The reason for this is that a
- zero is implied after and before the "and", similar to a one
- being implied between brackets.
