[JAVAscript]Math.random()?

[Gwei]

How effective is this fomula in getting
1(inclusive) to 100(inclusive) value at random?

Math.floor((Math.random()+0.01) * 100);

Any suggestion for better one?


Say, my math.random() gets 0.9999
I +0.01 it, and it gives 1.0999
then times 100, i get 100.99, after I math.floor it, it is 100 right? not 110.

function nrand(min,max){
  return Math.round(Math.random()*(max-min))+min;
}

Enjoy. This isn't uniform for values min and max, though.

This is:

function unrand(min,max){
  var n = min-1;
  while(n != min-1 && n != max+1) n = nrand(min-1,max+1);
  return n;
}
