WebJun 8, 2015 · I'm learning c++ and I'm trying to generate a random float and seem to be having some difficulties. I start by making a random int(), newRandom, between -100 and 100, then I take that newRandom and turn it into a random float, rand_X, between -1.0 and 1.0. The only caveat is I don't want rand_X to be between -0.2 and 0.2, in other words,

WebDec 6, 2024 · RAND_MAX is a very small number (typically 2^16). That means that from 23 bits of the floating point you make only 15 random. The others will be probably zero. You will indeed get random numbers in uniform distribution but of low precision. For example your random generator can generate 0.00001 and 0.00002 but cannot generate 0.000017.
