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)?
Consider the following simple program:It takes an (optional) string on the command line and prints it, with / characters replaced by _. This replacement functionality is implemented by the c_repl function1. For example, a.out foo/bar prints:
I have an array of signed short that I want to divide by 2048 and get an array of float as a result.I found SSE: convert short integer to float that allows to convert unsigned shorts to floats, but I want to handle signed shorts also.
