float cossp

(

float

a

)

Description:

The cossp function returns the cosine of a floating-point argument a. The angle a is expressed in radians. The return value is in the range of [-1.0 and +1.0]. An argument with a large magnitude may produce a result with little or no significance.

Parameters:

[in]

a

= Input float

Returns:

Resultant float

Special Cases:

• If | a | > 1.04858e+6, then the return value is zero for large angles.
