SE-0225 added isMultiple(of:) to BinaryInteger. I'm wondering if this change could be made more complete by discussing eg the following.

  • Should isMultiple(of:) also be added to BinaryFloatingPoint?

  • Should isPower(of:) be added to BinaryInteger and BinaryFloatingPoint?
    (Related discussion)

  • Should a family of methods like eg x.rounded(.towardZero, toMultipleOf: 8) and x.rounded(.up, toPowerOf: 2) be added to BinaryInteger and BinaryFloatingPoint?

Actually only isMultiple(of:) was added as per the announcement thread: [Accepted with Modifications] SE-0225: Adding isMultiple to BinaryInteger
