This chapter contains information about functions for performing mathematical computations, such as trigonometric functions. Most of these functions have prototypes declared in the header file `math.h'.
All of the functions that operate on floating-point numbers accept arguments and return results of type double . In the future, there may be additional functions that operate on float and long double values. For example, cosf and cosl would be versions of the cos function that operate on float and long double arguments, respectively. In the meantime, you should avoid using these names yourself. See Reserved Names.
