n1 is first multiplied by n2 producing an intermediate 32-bit result. n4 is the remainder and n5 is the floor of the quotient of the intermediate 32-bit result divided by the divisor n3.

none

A 32-bit intermediate product is used as for */ . n4 has the same sign as n3 or is zero. An ambiguous condition results if the divisor is zero or if the quotient falls outside of the range {-32,768..32,767}.
