Function `core.checkedint.adds`

Add two signed integers, checking for overflow.


						
				int adds
				(
				

				  int x,
				

				  int y,
				

				  ref bool overflow
				

				) pure nothrow @nogc @safe;
				

				

				long adds
				(
				

				  long x,
				

				  long y,
				

				  ref bool overflow
				

				) pure nothrow @nogc @safe;
				

				

				cent adds
				(
				

				  cent x,
				

				  cent 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.

Parameters

x	left operand
