Answer 2

Math.random() already provides a pseudorandom selection from 0 to one million. To get a random floating factor selection interior of a definite selection, first define the selection by utilising 'min' and 'max', then try this: min + (Math.random() * (max - min)) notice whether that this might in no way generate the optimum value. it would desire to come rather close, however the optimum value is genuinely no longer generated. in case you elect it to be possible to generate the optimum value, or you elect greater randomness than the equipped-in pseudorandom generator grants, there are uncomplicated procedures to construct greater stepped forward structures that cut back weaknesses like that. whether, in addition they'll take longer to run.

Answer 3

Math.random()



Will return a random number between 0 and 1



You multiply it by the largest number you want and you can round it to make it an integer.



so



function rnd(max)

{

return Math.Round(Math.Random() * max);

}
