Generating random numbers over a range in Go

Question

All the integer functions in math/rand generate non-negative numbers.

rand.Int() int              // [0, MaxInt]
rand.Int31() int32          // [0, MaxInt32]         


        

Answer 1

Solution that worked for me is: j = rand.Intn(600) - 100 where m is 100 and n is 500, it will generate numbers from -100 to 499.
