C/Math Toolchest
Technical Specifications:
The C/Math Toolchest (TM) library contains over 135 of the most often used functions in science and engineering. hlso included is GRAFIX (TM), a graphical data analysis program. Prebuilt libraries are included for the DOS versions of the C and C++ compilers from Mix ®, Borland ®, and Microsoft ®. For other compilers or operating systems, you must purchase the C/Math Library Source to build the library. You may also purchase the source code for the GRAFIX (TM) program. The C/Math GRAFIX Source is approximately 5000 lines of C code, 60% of which is a general purpose text and graphics library that can be used by your own programs.
