The tansp function returns the tangent of a floating-point argument a. The angle a is expressed in radians. 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 | > 2.50e+5, the return value may have no significance for large angles.
If a is INF (infinity), the return value is NaN (Not a Number).
