random number generator golang code example

Example 1: go random number

import (
	"math/rand"
)

rand.Intn(10)

Example 2: go rand seed

rand.Seed(time.Now().UTC().UnixNano())

Example 3: random number golang

// Uniform Random int (min <= x <= max)
x = rand.Intn(max - min) + min

// Uniform random float (0 <= x <= 1)
x = rand.Float64()  

// Uniform random float (min <= x <= max)
x = (rand.Float64() * (max - min)) + min

Example 4: go generate random number

rand.Intn(max - min) + min
