Thanks guys for the cogent clarifications..I will now forget about converting to float32 on 64-bit CPUs
I'm in the process of converting my often-used C-code apps to Go because I see tremendous advantages of Go vs C. I've been using C,C++ for many years and only recently discovered Go... My Go knowledge is 100% self-taught and entirely based on Go web docs, tutorials, blogs etc A good doc on "C to Go code conversion",would help me greatly, so if anyone knows of one, I'd appreciate knowing about it I'm somewhat reluctant to use software based conversion On Mon, Apr 22, 2019 at 8:55 AM Marvin Renich <m...@renich.org> wrote: > * lgod...@gmail.com <lgod...@gmail.com> [190421 21:56]: > > ??
