Mathematics <math.h>

The functions described in this section evaluate various standard mathematical functions such as logarithms, sines, cosines etc. The header also defines the macro HUGE_VAL as a double expression that is returned as the result of some of the functions in certain conditions.

When using the mathematical functions, and real arithmetic in general, it is worth bearing in mind that some of the range of C6000 processors do not have hardware floating-point instructions, and that all floating-point operations on them must be carried out by software routines. This has inevitable implications on performance.
