Description
mul24 multiplies two 24-bit integer values x and y. x and y are 32-bit integers but only the low 24-bits
are used to perform the multiplication. mul24 should only be used when values in x and y are in the
range [-223, 223-1] if x and y are signed integers and in the range [0, 224-1] if x and y are unsigned
integers. If x and y are not in this range, the multiplication result is implementation-defined.
