Hello there,
I'm using fixed-point arithmetic in an algorithm. I am troubled by the
inefficiency of the fixed-point multiplication and division operations on
32-bit architectures. On the Intel 64-bit architecture, I can use the
Nativeint module and it's quite fast, on 32-bit I had to use the Int64
module (for the necessary shifts and mul/div's) and I encountered a
significant slowdown, naturally. is there a preferred way of performing
fixed point arithmetic with ocaml on 32-bit architectures that I might be
overlooking?
Best,
--
