WebTo fill a float is reasonable, for all bits. float has only 23 bits for the number, plus 8 for exponent. If you use double you will be mislead and overconfident in the capacity of this function. If you need a true double, consider using /dev/urand or other proper true random number generator (TRNG). WebApr 6, 2014 · To make this understand easier: let's say you want a random number in the range of 0..5. Using 3 random bits, this would produce the numbers 0..1 with double probability than from the range 2..5. Using 5 random bits, numbers in range 0..1 would occur with 6/32 probability and numbers in range 2..5 with 5/32 probability which is now …

WebDec 18, 2024 · The illustration above shows the problem. In the example, we intend to generate a random integer value in the range -1 to 1. If we base our integer on a random real that goes precisely to the endpoints, the min and max integers only get half the probability of being chosen. Rounding to the 0 integer value happens half of the time, … WebNov 16, 2012 · This may have really bad rounding properties. rand () returns a 32-bit int, which you're casting to a 32-bit float, which will cause values to be quantized. For example, it's 64 times more likely that you'll get the value 1000000192 than the value 1, since 1000000161 through 1000000223 all round to 1000000192.

WebFeb 11, 2024 · So for example if we have 52 letters, it requires 6 bits to represent it: 52 = 110100b. So we will only use the lowest 6 bits of the number returned by rand.Int63().
