Module Fpu_rename_all

module Fpu_rename_all: sig .. end
Aliases floating point functions to their "constant" counterparts.

As described in the Fpu module documentation, there are problems when mixing some C-lib or ocaml native functions with interval programming on 64 bits machine.

The standard floating point functions results will always lie in the low; high interval computed by the Fpu module, but they are slightly different on 32 and 64 bits machines.

Using Open Fpu_rename_all at the beginning of your program guarantees that floating computation will give the same results on 32 and 64 bits machines. This is not mandatory but might help.

NB: while most transcendantal function are almost as fast, and sometimes faster than their "standard" ocaml counterparts, +. -. *. and /. are much slower (from 50% to 100% depending on the processor. If you want to rename transcendantal functions but not +. -. *. and /. then use the Fpu_rename module.
