mulu

Multiply two unsigned integers, checking for overflow (aka carry).

The overflow is sticky, meaning a sequence of operations can be done and overflow need only be checked at the end.

  1. uint mulu(uint x, uint y, bool overflow)
  2. ulong mulu(ulong x, uint y, bool overflow)
  3. ulong mulu(ulong x, ulong y, bool overflow)
