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)

    uint
    mulu
    (
    uint x
    ,
    uint y
    ,
    scope ref 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)

Parameters

x uint

left operand

y uint

right operand

overflow bool

set if an overflow occurs, is not affected otherwise

Return Value

Type: uint

the product
