At least on intel, float64 should be faster than float32 since all math is done on the fpu in 64 bits, so it needs to be converted, but the memory bus also comes into play.
I would doubt it. Float32 is designed for size not performance. > On Apr 21, 2019, at 8:55 PM, lgod...@gmail.com wrote: > > ??
