The math routines perform common mathematical calculations. Most of these routines work with floating-point values and therefore include the floating-point libraries and support routines.
All of these routines are implemented as functions. Most are prototyped in the include file MATH.H. Functions which end in 517 (acos517, asin517, atan517, cos517, exp517, log517, log10517, sin517, sqrt517, and tan517) are prototyped in the 80C517.H include file. The rand and srand functions are prototyped in the STDLIB.H include file. The _crol_, _cror_, _irol_, _iror_, _lrol_, and _lror_ functions are prototyped in the INTRINS.H include file.
