如何生成随机的Uint32 Go

Question

I need to generate random Uint32 type, I know how to do in int but because of high numbers cause an overflow.

is it possible to generate random Uint32 in min and max range?

Answer 1

You can just call the standard library:

https://golang.org/pkg/math/rand/#Uint32

To force it within a range, you can use modulu and plus

Example:

func randU32(min, max uint32) uint32 {
    var a = rand.Uint32()
    a %= (max - min)
    a += min
    return a
}
