                         by Martin Sander 1996-1999

1. What is CMATH?
-----------------
CMATH is a comprehensive library for complex arithmetics and mathematics.
Superior speed, accuracy and safety are achieved through the implementation
in Assembly language.

Each of the three floating-point accuracies (Single, Double, and Extended)
is given its own, optimized version of each function.


2. System requirements
----------------------
This version of CMATH is designed for IBM AT, PS/2 or compatibles,
equipped at least with a 80386 CPU and a 80387 coprocessor.
Depending on your choice when downloading or ordering, you got the
version for

- Borland (Turbo) Pascal, version 7.0;
  Shareware version:  for real-mode DOS.
  Registered version: real-mode DOS, DPMI, Windows 3.x; separate libraries
  optimized for all processors from 486DX/Pentium down to 286 with or
  without coprocessor.

- Borland Delphi 2, 3, or 4.
  Shareware version:  units back-compatible to 386+387
  Registered version: additionally faster units, optimized for
                      Pentium/Pentium II, back-compatible to 486DX


3. Installation
---------------
Please run the installation program INSTALL.EXE. If anything goes wrong,
you may try the following:
   a) Create the directory where you want CMATH to reside.
   b) Manually unzip the file DOC.ZIP into it.
   c) Pascal:
      Create a sub-directory \UNITS and unzip the file UNITS.ZIP into it.
      Delphi:
      Create a sub-directory \LIB and unzip the file LIB.ZIP into it.

If you don't succeed that way, you probably got a corrupted download.
Please download again. If even that does not help, please contact:
MartinSander@Bigfoot.com.

After you completed the installation, you must set the Units search path
according to your CMATH directory choice:
Add these paths to the standard settings in the menu
"Options/Directories"         in Borland Pascal,
"Project/Options/Directories" in Delphi.
(Remember: a semicolon is used to separate entries in these fields.)
If you use the command-line compilers BPC.EXE or DCC32.EXE, you must
add this path also in the configuration files, BPC.CFG or DCC32.CFG.


4. Running the Example
----------------------
See chapter 2 of CMATH.TXT, "Getting Started".
Check your installation by compiling and running CDEMO.PAS. Follow the
instructions in the header of that file.
If you get errors like "Unknown Function ...", you probably did not set
the unit search path correctly.


5. Documentation
----------------
The full CMATH documentation is to be found in the file CMATH.TXT as
ASCII text. If you want to load the documentation into a word processor
under Windows, you must use the filter "ASCII text" or "MS DOS text".

7. Registered Version
---------------------
If you like CMATH and decide to use it, please be fair and register.

a) The registered version of CMATH for Borland Pascal

-  supports all targets of Borland Pascal 

-  has individually optimized libraries for three degrees of
   processor backward-compatibility:
      486DX/Pentium+
      386+ (coprocessor required)
      286+ (no coprocessor required; the 286 version of course only in 16-bit)

-  costs USD 25  or  EUR  19  per unit,
         plus a mailing fee of  $5 or EUR 5.

   and can be ordered directly from the author (e-mail or a printout
