Function rational_from_integer 

pub fn rational_from_integer(n: &IBig) -> RBig

Construct an RBig from an integer value.

Equivalent to n / 1 — the result satisfies rational_is_integer(&rational_from_integer(n)) == true.

Examples

use oxinum_rational::{rational_from_integer, rational_is_integer};
use dashu_int::IBig;
let r = rational_from_integer(&IBig::from(42));
assert!(rational_is_integer(&r));
