Re: [go-nuts] Mathematical operations - the generics way
I don't know if it's important to you, but your Max[float64] isn't
compatible with math.Max in the standard library.
For example, Max[float64](NaN, 1) returns 1 rather than NaN.

Re: [go-nuts] Mathematical operations - the generics way
I found a working version meantime.
// Max returns the bigger value between two numbers.
func Max[T constraints.Ordered](x, y T) T {
if x > y {
return x
}
return y
}
// Abs returns the absolut value of x.
func Abs[T constraints.Signed | constraints.Float](x T) T {
if x < 0 {
return -x
}
return x
}

[go-nuts] Mathematical operations - the generics way
Now that generics are officially supported, I was checking in the Go source if there are some generic implementation of utility methods like Abs, Min, Max etc, but I couldn't find it other than this proposal https://github.com/golang/go/discussions/48287. Anyone knows if something related has been adopted and implemented in Go 1.18? -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
