If s is parsed as (n, l, u), then n is the nearest approximation of s with the desired precision. Moreover, l and u are the most precise float such that l <= s <= u, again with this precision.

Consistent with logic_real definition in Cil_types.

exception Float_Non_representable_as_Int64 of sign
val truncate_to_integer : float -> Integer.t
Raises Float_Non_representable_as_Int64 if the float value cannot be represented as an Int64 or as an unsigned Int64.
