Function Documentation

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
LAn integer between 1 and 4 included that qualify the dimension of the vector.
TSigned or unsigned integer scalar types.
