1. Introduction
---------------
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 and DPMI; separate libraries
  optimized for either 486DX/Pentium+ or 386+387

- Borland Delphi 2, 4, or 5.
  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 you don't like the directory structure created by INSTALL.EXE, you
can change it "by hand" to your liking after the completed installation.

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 1.4 of CMATH.HTM, "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.HTM
to be read with a browser like Netscape or IE.

6. What's New?
--------------
The present release introduces the classes "polar" of float, double,
and extended precision, along with a whole range of functions and operators
in polar coordinates. As a consequence, the member function "polar" of the
cartesian complex classes had to be replaced by "magargtoc".
