## Fastest precise way to convert a vector of integers into floats between 0 and 1

Consider a randomly generated __m256i vector. Is there a faster precise way to convert them into __m256 vector of floats between 0 (inclusively) and 1 (exclusively) than division by float(1ull<<32)?

## What is the true maximum (and minimum) value of Random.nextGaussian()?

In theory, the bounds for nextGaussian are meant to be positive and negative infinity. But since Random.nextDouble, which is used to calculate the Gaussian random number, doesn't come infinitely close to 0 and 1, there is a practical limit to nextGaussian. And Random.next is also not a perfectly uniform distribution.
