nv-number-rational
===============
- nv-number-rational
- change to bigint only
- its slow, for nvlang test

install
=======
- npm install nv-number-rational

usage
=====

example
-------

const {R} = require("nv-number-rational");

var r0 = new R(2n,3n)
var r1 = new R(4n,6n)

/*
> r0
R [2/3] {}
> r1
R [2/3] {}
>
> r0.eq(r1)
true
>
*/

var r2 = new R(1n,4n)
/*
> r1.add(r2)
R [11/12] {}
>
*/

> r1.sub(r2)
R [5/12] {}
>

> r1.mul(r2)
R [1/6] {}
>

> r1.div(r2)
R [8/3] {}
>

> r1.inv()
R [3/2] {}
>
> r1.pow(3)
R [8/27] {}
>

> r = new R(4n,1n)
R [4/1] {}
> r.fac()
R [24/1] {}

// if expo is not Interger
// it is slow, coz use generator ,and create many Object, just for test
var expo = new R(1n,2n)
R [1/2] {}
> r.pow(expo)
