Function Documentation

findNSB()

GLM_FUNC_DECL int glm::findNSB	(	genIUType	x,
		int	significantBitCount
	)

Returns the bit number of the Nth significant bit set to 1 in the binary representation of value.

If value bitcount is less than the Nth significant bit, -1 will be returned.

Template Parameters

genIUType

Signed or unsigned integer scalar types.
