Function core.checkedint.addu

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

uint addu (
  uint x,
  uint y,
  ref bool overflow

ulong addu (
  ulong x,
  ulong y,
  ref bool overflow

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


x left operand
y right operand
overflow set if an overflow occurs, is not affected otherwise


the sum
