Aliases floating point functions to their "constant" counterparts, including +., -., *. and /..

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.
