Function Documentation

float atan2sp	(	float	a,
		float	b
	)

Description:

The atan2sp 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]	a	= Input float
[in]	b	= Input float

Returns:

Resultant float

Special Cases:

• If a or b is NaN (Not a Number), the return value may be random.
• If | a/b | < 2.44e-4, then the return value is a/b for small angles.
