Proposal here: Draft of relaxed floating-point operators. by stephentyrone · Pull Request #3545 · swiftlang/swift-evolution · GitHub Summary of changes Define operators on floating-point types that permit the compiler to apply "normal" algebraic transformations that make it easier for users to explicitly trade-off bitwise reproducibility for improved performance. Motivation Consider the following function: func foo(a: Float, b: Float, c: Float, d: Float) -> Float { a*b + c + d } Evaluatin...
