type
t
exception Too_big
Produced by values whose physical representation is too
costly (e.g. in terms of memory usage).

faster, but produces correct results only when b evenly divides a.

Raises Failure
if the argument does not fit in an OCaml int
val to_float : t -> float
val of_float : float -> t
Converts from a floating-point value. The value is truncated.
Raises Overflow
on infinity and NaN arguments. (Or on big values
with Big_int.)
