[swift-users] Why no unsafeRemainder(dividingBy: Self) in FixedWidthInteger?

[Jens Persson via swift-users]

I have some integer processing code that is called very intensively and
need to be as fast as possible, I therefore use &+ &- &/ &* instead of + -
/ * which results in a significant speedup.

However, I also need to use % and I noticed that there is no &% ...

That is, FixedWidthInteger has:
func remainderReportingOverflow(dividingBy: Self)

but there is no:
func unsafeRemainder(dividingBy: Self)

which is different from the other …ReportingOverflow-unsafe…-pairs:

func addingReportingOverflow(Self)
func subtractingReportingOverflow(Self)
func dividedReportingOverflow(by: Self)
func multipliedReportingOverflow(by: Self)

func unsafeAdding(Self)
func unsafeSubtracting(Self)
func unsafeMultiplied(by: Self)
func unsafeDivided(by: Self)

Is this intentional and if so why?

/Jens
