Installation: Run Setup.exe and follow instructions.
Includes Uninstaller.

Status: Freeware, freely distributable

This is a small Scientific Calculator that supports full precedence.
Currently it does not support Exponential Notation, but does include
a number of functions, Clipboard Support, History of results and more.

A standalone Executable is included. The Source Directory is the Delphi 4
source code.

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.

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. x^1/y (i.e. the y-th root of x) can be calculated using INV and x^y
buttons.

5. Inverse exist for all the Trigonometric functions by using the INV
button than one of SIN, COS or TAN buttons.

6. The Radian/Degree toggle, the number of decimal places and the contents
of Memory are saved to the Registry.

7. 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.

8. Decimal Point and Thousand's separator should be displayed in what ever
character the Regional Settings of your MS Windows 95/98/NT 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.

9. ESBCalc executable is now ASPack'ed. If you rebuild the executable it
will be much larger than the one supplied. Get a copy of ASPack from:

http://www.alenka.spb.ru/aspack

It's free for non-commercial use and only $29 to register for commercial
use. We are registered users.

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.

Notes on Source
===============

ESBCalc uses the new features of Delphi 4 (Dynamic Arrays).
The user interface is made up almost entirely of LMD Tools 4.5
components.

To recompile the source you need:

- Delphi 4 Professional or C/S (as the Math Unit is used)
- LMD Tools 4.5
- Aleksey Xacker's CaptBtn (included)

A Trial version of LMDTools 4.5 is available from:

http://www.lmdtools.com

Licensing
=========

Developers are free to use the code as you see fit, however an Email or
Postcard would be nice, as would a reference to our web site included on
our web site or in your docs. Though none of this is obligatory.

You are, however, specifically prohibited from charging, or requesting
donations, for any copies of this program as it stands; if you wish to
include it on a CD that is sold at a reasonable price please notify us
of your intent by email - we normally are happy to grant permission.

ESB Consultancy makes no guarantees regarding the capabilities
nor the "Safeness" of this code. It is free after all, so you take
all the risks :-)

ESB Consultancy makes no promise of support for this code, however we
are happy to receive Email comments

OTHER PRODUCTS
==============

ESBPDFÖ Analysis
================

Provides everything needed for using Discrete & Continuous Probability
Distributions in a single application. Most Tables and supplied functions
(such as in MS Excel) give P(X <= A) and using algebra other results can
be found whereas ESB PDF Analysis handles all the Probability combinations
for you.

Features include: Binomial, Poisson, Normal, Exponential, Student t, Chi
Squared and F Distributions; Inverses of the Normal, Student t, Chi Squared
and F Distributions; Lists of Binomial Coefficients, Factorials,
Permutations; Fully Customisable; Integrated Help System which includes
a Tutorial.

We also plan on adding many more Distributions and features. Ideal for the
Maths/Stats Student who wishes to understand Probability Distributions
better, as well as the Maths Buff who wants a well designed calculating
tool.

Fully Functional Trial version available from our web site.
