The sindp function returns the sine 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 double
Returns:
Resultant double
Special Cases:
If | a | < 9.536743e-7, the return value is W for small angles.
If | a | > 1.0737e+9, the return value is zero for large angles.
