double atan2dp	(	double	a,
		double	b
	)

Description:

The atan2dp function returns the arc tangent of a floating-point argument a/b. The return value is an angle in the range [-PI/2, PI/2] radians.

Parameters:

[in]	b	= Input double

Returns:

Resultant double

Special Cases:

• If a or b is NaN (Not a Number), the return value may be random.
• If | a/b | < 1.49e-8, then the return value is a/b for small angles.
