How random is Math. random()? It may be pointed out that the number returned by Math. random() is a pseudo-random number as no computer can generate a truly random number, that exhibits randomness over all scales and over all sizes of data sets.
random() returns a value to 16 decimal places, meaning values between 0.33-0.34 and between 0.66-0.67 will not be assigned a value.
The Math. random() function returns a floating-point, pseudo-random number that's greater than or equal to 0 and less than 1, with approximately uniform distribution over that range — which you can then scale to your desired range.
The Math. random() method returns a random number from 0 (inclusive) up to but not including 1 (exclusive).
Math.random() generates a floating point number of 16 decimal places greater than or equal to zero and less than 1.
