4.1 Floating Point Numbers
The Math Library allows your application to use floating point (FP) numbers. C Developers will find little reason to make direct calls to functions in the Math Library as most of this functionality is taken care of for you in the C environment. (An exception is conversions from FP numbers to ASCII text characters and use of special date-time routines.) Assembly developers, however, will find direct use of the functions and structures in the Math Library essential.
The latter half of this chapter (from this point on) is provided for Assembly developers who need more complete information about the intricacies of the Math Library. Much of this information may also be useful for C developers who wish to make direct calls to the functions in this library for optimization purposes.
