Can JavaScript's Math.random() ever return exactly a 0 or 1?

JavaScript Random 1 Math.random (). Math.random () always returns a number lower than 1. 2 JavaScript Random Integers. Math.random () used with Math.floor () can be used to return random integers.

This JavaScript function always returns a random number between min (included) and max (excluded): Example. function getRndInteger (min, max) {. return Math.floor(Math.random() * (max - min) ) + min; }.
You can use Math.round (Math.random ()). If Math.random () generates a number less than 0.5 the result will be 0 otherwise it should be 1. Thank you for saving me brain cells. :) @Combine Should that be let oneOrZero = (Math.random ()>=0.5)? 1 : 0;? There is a +1 with Math.random, so it will always going to add 1 to the randomly generated number.

Yes to 0, no to 1.

Returns a floating-point, pseudo-random number in the range [0, 1) that is, from 0 (inclusive) up to but not including 1 (exclusive), which you can then scale to your desired range.

From the ECMAScript specification:
Returns a Number value with positive sign, greater than or equal to 0 but less than 1, chosen randomly or pseudo randomly with approximately uniform distribution over that range, using an implementation-dependent algorithm or strategy. This function takes no arguments.
