Function core.checkedint.addu
Add 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.
Prototypes
uint addu( uint x, uint y, bool overflow ) pure nothrow @nogc @safe; ulong addu( ulong x, ulong y, bool overflow ) pure nothrow @nogc @safe;
Parameters
| Name | Description |
|---|---|
| x | left operand |
| y | right operand |
| overflow | set if an overflow occurs, is not affected otherwise |
Returns
the sum
