How do computers pick random numbers
WebJust changing this number by one will cause a completely different sequence of random numbers to be generated. So let's call the previous number (or the seed when generating the first one) P. Then our next random number, let's call it R, is. R = a * P + c (mod m). So we have a couple more letters here, a, c and m. WebTo generate a random real number between a and b, use: =RAND ()* (b-a)+a. If you want to use RAND to generate a random number but don't want the numbers to change every time …
