functions (including Trigonometric, Hyperbolic, & Logarithmic - Base 10,
Base 2 & Natural), Paper Trail, Clipboard Support, History of results and
more.
ESBCalc Pro: if you would like a more featured Scientific Calculator with
Exponential Notation, enhanced Paper Trail, more customisation, user defined
constants, online help and more, then check out ESBCalc Pro - only $19USD

Notes on the Calculator
=======================
1. Results are only entered into the History List when the "=" button is
pressed. Only the last 10 items are remembered and these are stored in the
registry. There is also the option in the History list to clear previous
items. The History List only stores displayed values not the internal values.
2. 10^x can be calculated using INV and LOG buttons, or by entering 10
and then using the x^y button.
3. e^x can be calculated using INV and LN buttons, or by pressing the
"e" button and then using the x^y button
4. 2^x can be calculated using INV and LG2 buttons, or by entering 2
and then using the x^y button.
5. x^1/y (i.e. the y-th root of x) can be calculated using INV and x^y
buttons.
6. Inverse exist for all the Trigonometric functions by using the INV
button than one of SIN, COS or TAN buttons.
7. Hyperbolic functions are done by first pressing the HYP button and
then one of SIN, COS or TAN buttons.
8. Inverse Hyperbolic Functions are done by pressing INV then HYP (order
does not matter so HYP then INV is also okay) then one of SIN, COS or
TAN buttons.
9. The Radian/Degree toggle, the number of decimal places and the contents
of Memory are saved to the Registry. As is the History. The contents of
the Paper Trail are not saved.
10. Using the Thousand's separator is on by default - use the option button
next to the Memory display to change this. Copying and pasting results
with Thousand's separators may upset some edit fields.
11. Decimal Point and Thousand's separator should be displayed in what ever
character the Regional Settings of your MS Windows 9X/NT/2000/XP is setup
for. If you expect to see a ',' for a decimal point but don't then you may
still have US (or something similar) settings.
12. When using XP Style Buttons under Windows XP, the colour options for the
buttons will be ignored.
13. Last Error (under info button) displays details about the last error that
occurred. AC clears this.
14. % functions as an infix operation, thus 25 % 10 calculates 10% of 25 and
would return 2.5 - it does not currently support operations such as 25 + 10 %
which some calculators interpret to mean add 10% of 25 to 25 thus 27.5
Keyboard Shortcuts:
Besides the obvious ones:
/ - same as divide button
^ - same as power (x^y) button
A - same as AC - All Clear - button
C - same as C - Clear - button
_ - same as change sign button
Also hitting Enter/Return is the same as hitting the equals button.
Known Problems
==============
1. Due to the lack of support for Scientific Notation, ESBCalc does sometimes
cause "funny" things to happen when number get too large. Check out ESBCalc Pro
if you need to play with bigger numbers.
2. ESBCalc may not view correctly when cetrain "Large Fonts" are used and
certain Themes. Try selecting a different Font and/or Theme. We improved on
this significantly with v4.
3. When dealing with a large number of digits and having thousands separators on
can cause the fields to "overflow". Try adjusting Font and/or Font Size till
you find one that you are happy with.
