Functions

func WasmCompatMax

func WasmCompatMax(x, y float64) float64

WasmCompatMax is the Wasm spec compatible variant of math.Max

This returns math.NaN if either parameter is math.NaN, even if the other is math.Inf.

See https://github.com/golang/go/blob/1d20a362d0ca4898d77865e314ef6f73582daef0/src/math/dim.go#L42-L59

func WasmCompatMin

func WasmCompatMin(x, y float64) float64

WasmCompatMin is the Wasm spec compatible variant of math.Min

This returns math.NaN if either parameter is math.NaN, even if the other is -math.Inf.

See https://github.com/golang/go/blob/1d20a362d0ca4898d77865e314ef6f73582daef0/src/math/dim.go#L74-L91

func WasmCompatNearestF32

func WasmCompatNearestF32(f float32) float32

WasmCompatNearestF32 is the Wasm spec compatible variant of math.Round, used for Nearest instruction. For example, this converts 1.9 to 2.0, and this has the semantics of LLVM's rint intrinsic.

Ex. math.Round(-4.5) results in -5 while this results in -4.

See https://llvm.org/docs/LangRef.html#llvm-rint-intrinsic.
