you could do it with side effects on the arguments.

That kind of defeats the original purpose of utilising the fact that -- for every processor I'm knowledgeable of; though that's not a huge sample -- at the machine code level, DIV instructions produce both quotient and remainder as the result of a single operation.

From the Intel manual:

DIV—Unsigned Divide

Description: Divides unsigned the value in the AX, DX:AX, EDX:EAX, or RDX:RAX registers (divi- dend) by the source operand (divisor) and stores the result in the AX (AH:AL), DX:AX, EDX:EAX, or RDX:RAX registers.

The two operations of finding quotient and remainder of one number divided by another are so often used in concert with each other, it seems a waste to have to perform the division twice to get at both parts.

(Just for the fun of it in autoboxing notation...)

Yuck! What a waste of cpu :)
