Generate random float numbers in range PHP

Question

I have a code that initializes a dice object by the following code:

public function initializeDiceSides($totalSides, $fair, $maxProbability = 100) {
   $maxT         


        

Answer 1

I'd just generate random numbers from 0 to 999999 and then divide them by 100000

Answer 2

You could multiply the variables that you feed into mt_random by a factor of, say, 100000, and then divide the output by the same factor to get a float value.

Answer 3

function random_float($min = 0, $max = 1, $includeMax = false) {
    return $min + \mt_rand(0, (\mt_getrandmax() - ($includeMax ? 0 : 1))) / \mt_getrandmax() * ($max - $min);
}

Answer 4

Make sure the value of $maxProbability and $totalSides are floats.
If they are integers, the result will be typed as an integer.

Answer 5

A simple approach would be to use lcg_value and multiply with the range and add the min value

function random_float ($min,$max) {
    return ($min + lcg_value()*(abs($max - $min)));
}
