Function core.checkedint.subs

Subtract two signed integers, checking for overflow.

int subs (
  int x,
  int y,
  ref bool overflow

long subs (
  long x,
  long 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 difference
