Function Documentation

findNSB()

GLM_FUNC_DECL vec<L, int, Q> glm::findNSB	(	vec< L, T, Q > const &	Source,
		vec< L, int, Q >	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

L	An integer between 1 and 4 included that qualify the dimension of the vector.
T	Signed or unsigned integer scalar types.
