Javascript math floor math random.

Try it yourself. Yes the results will be evenly distributed. In a nutshell one calls math floor when you want to truncate a decimal value to its nearest integer by just dropping the decimal portion. Math random will always generate a number that is strictly less than 1 i e 0 x 1 so math floor math random 255 will generate a random number between 0 and 254.

Math floor null returns 0 not a nan. The max min 1 is the logic that creates the range. When you add the min at the end you are adding the 2 to your range and end up with a random number from 2 to 10. Math random used with math floor can be used to return random integers.

The floor method rounds a number downwards to the nearest integer and returns the result. Return a random number between 1 and 10. The math random function returns a floating point pseudo random number in the range 0 to less than 1 inclusive of 0 but not 1 with approximately uniform distribution over that range which you can then scale to your desired range. If the passed argument is an integer the value will not be rounded.

So 3 9 becomes 3 2 1 becomes 2 etc. So you would typically use that when you need an integer and you want the integer that is smaller than or equal to the decimal value.
