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, ref bool overflow)
  2. ulong mulu(ulong x, uint y, ref bool overflow)
  3. ulong mulu(ulong x, ulong y, ref bool overflow)
  4. ucent mulu(ucent x, ucent y, ref bool overflow)
    pragma(inline, true)
    ucent
    mulu
    ()
    (
    ucent x
    ,
    ucent y
    ,
    ref bool overflow
    )

Parameters

x
Type: ucent

left operand

y
Type: ucent

right operand

overflow
Type: bool

set if an overflow occurs, is not affected otherwise

Return Value
