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, bool overflow)
  2. ulong mulu(ulong x, uint y, bool overflow)
  3. ulong mulu(ulong x, ulong y, bool overflow)
  4. ucent mulu(ucent x, ucent y, bool overflow)
    nothrow @safe @nogc pure pragma(inline, true)
    static if(is(ucent))
    ucent
    mulu
    (
    ucent x
    ,
    ucent y
    ,
    scope ref bool overflow
    )

Parameters

x ucent

left operand

y ucent

right operand

overflow bool

set if an overflow occurs, is not affected otherwise

Return Value

Type: ucent

the product
