What is the rand.Seed() function in Golang?
In Golang, the rand.Seed() function is used to set a seed value to generate pseudo-random numbers.
If the same seed value is used in every execution, then the same set of pseudo-random numbers is generated. In order to get a different set of pseudo-random numbers, we need to update the seed value.
Syntax
rand.Seed(value)
Parameters
The rand.Seed() function accepts the following parameter:
value: This is the value that is set as the seed value.
Example
The code given below will show us how to use the rand.Seed()function to set the seed value:
package mainimport ("fmt""math/rand""time")func main() {// seed to get different result every timerand.Seed(time.Now().UnixNano())fmt.Println(rand.Intn(50))fmt.Println(rand.Float64())}
