Does math.random() actually return exact 0 or 1 ever?

Question

In java or any other language where math.random() works... can someone tell me if math.random() is able to return an exact zero or 1.... or it can return in between..... 0.00000000001 and 0.9999999999.. Any help regarding this topic is appreciated.

Answer 1

Math.floor((Math.random() * 10) + 1);
return a value with 1 to 10

Math.floor(Math.random() * 10);
return a value with 0 to 9

Answer 2

For practical coding I think Arthur already gave you tools to help you get 0 and 1 when using math.random(). But I find your question interesting so let's see... For starters, math.random() can never return 1 because it returns floats between 0 and 1, 1 not included. So in theory, yes it can return exactly 0. But with all those floats to choose from, what are the odds?

Answer 3

Math.floor(Math.random() * 2);
0 or 1.

Answer 4

Thnx fr the help Arthur Bacci ... It means this func returns (0<=x<1) right?

Answer 5

a simple look into the java docs would have answered your question...

"Returns a double value with a positive sign, greater than or equal to 0.0 and less than 1.0."
