bettermath

introduction

the safer integer in js is 9007199254740991.

we can see this number big but I was limited for my RSA system. So I've reinvent the number in js: number are array. Each numberarray are compose like this

// realnumber:
let mynum = 23
// arraynumber:
let mynum = [3,2]

the number are reverst because it's more easier to manipuling this. But don't worry using the transform and intoString methods you havn't to read inverse Array of number

example

const bmath = require("bettermath")
let num1 = bmath.transform(9007199254740991)
let num2 = bmath.add(num1, bmath.transform(1) /* or [1]*/)
console.log(bmath.intoString(num2)) // return 9007199254740992
console.log(bmath.isEqual(num1, num2)) // return false

docs

.transform

return a Array

transform number in to Array ex:

bmath.transform(45) // return [5, 4]

.add

return an Array

add tu Arraynumber ex:

bmath.add([5, 4], (5, 4)) // returnn [0, 9]

.intoString

return a String

transform Arraynumber in String ex:

bmath.intoString([5, 4])// return 45

.intoNumber

exactly like intoString but it's return Number can be NaN and Infinite

.isInferieur .isSuperieur .isEqual

for compare to Arraynumber

return boolean ex:

bmath.isEqual([5, 4],[5, 4]) // return true

.reduce

reduce Arraynumber with 0 useless

return an Array

bmath.reduce([1,0]) // return [1]

.sub

substract 2 Arraynumber

return an Array ex:

bmath.sub([5, 4], [1]) // return [4, 4]

.mul

multiply 2 Arraynumber

return an Array ex:

bmat.mul([2],[3]) // return 6

.div

divide to number (euclidienne)

return an object like this {result:[x], modulo:[x]} ex:

bmat.div([4],[3]) // return {result: [1], modulo:[1]}

WARNING this project accept juste positive and not comma number

if you want to add somthing to the project go on github and good luck because this are brainfuck.
