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. delete git branch locally https://uptimesg.com
