# bitmask(bool4)

> Returns a bitmask representation of a bool4. Storing one 1 bit per component in LSB order, from lower to higher bits (so 4 bits in total). The component x is stored at bit 0, The component y is stored at bit 1, The component z is stored at bit 2, The component w is stored at bit 3 The bool4(x = true, y = true, z = false, w = true) would produce the value 1011 = 0xB
