These are already included with SE-0067, we’re just working on finishing up the implementation.
/// Remainder of `self` divided by `other`. This is the IEEE 754 remainder /// operation. /// /// For finite `self` and `other`, the remainder `r` is defined by /// `r = self - other*n`, where `n` is the integer nearest to `self/other`. /// (Note that `n` is *not* `self/other` computed in floating-point /// arithmetic, and that `n` may not even be representable in any available /// integer type). If `self/other` is exactly halfway between two integers, /// `n` is chosen to be even. /// /// It follows that if `self` and `other` are finite numbers, the remainder /// `r` satisfies `-|other|/2 <= r` and `r <= |other|/2`. /// /// `remainder` is always exact. func remainder(dividingBy other: Self) -> Self /// Mutating form of `remainder`. mutating func formRemainder(dividingBy other: Self) /// Remainder of `self` divided by `other` using truncating division. /// Equivalent to the C standard library function `fmod`. /// /// If `self` and `other` are finite numbers, the truncating remainder /// `r` has the same sign as `other` and is strictly smaller in magnitude. /// It satisfies `r = self - other*n`, where `n` is the integral part /// of `self/other`. /// /// `truncatingRemainder` is always exact. func truncatingRemainder(dividingBy other: Self) -> Self /// Mutating form of `truncatingRemainder`. mutating func formTruncatingRemainder(dividingBy other: Self) /// Square root of `self`. func squareRoot() -> Self /// Mutating form of square root. mutating func formSquareRoot() /// `self + lhs*rhs` computed without intermediate rounding.
