math.h — Math Functions
The standard math functions have been augmented by implementations
for the float data type, and in some cases for the fract16 data type.
Table 4-4 provides a summary of the functions defined by the
header file. Descriptions of these functions are given under the name of
the version in the
double
This header also provides prototypes for a number of additional math
functions

These functions are described in
page 4-22. .
