Function Documentation

float powsp	(	float	a,
		float	b
	)

Description:

The powsp function returns the a power of b function. The return value is the number a^b.

Parameters:

[in]	a	= Input float Base
[in]	b	= Input float Power

Returns:

Resultant float

Special Cases:

• If a or b is NaN (Not a Number), the return value may be random.
• If b = 0, return 1.0 (a is ignored).
• If a < 0, and b is not an integer value, then NaN is returned.
• If a = 0, and b < 0, return value is 0 for Asm, Infinity for C/Inline/Vector.
• If |a| = Inf, b < 0, return value is Inf for Asm, 0 for C/Inline/Vector.
• If a = b = 1.175494351E-38, return value is 0 for Asm, 1 for C/Inline/Vector.
