BetterStrint

BetterStrint – a JavaScript library for string-encoded integers

BetterStrint is a plug-in designed to deal with arbitrarily large integers. The core inspiration comes from the implementation of strint, so BetterStrint API is generally compatible with strint. More importantly, BetterStrint also extends some functions

Support the calculation of positive and negative numbers (addition, subtraction, multiplication, division, etc.), comparison (greater than less than, etc.)

Install

npm install better-strint -S

import BetterStrint from 'better-strint'
 
console.log(BetterStrint.add("123","456"))  // 579

API

方法名	说明	参数:类型
abs(x)	返回参数 x 绝对值	string
add(x, y)	返回 x + y 的值	x : string , y : string
div(x, y)	返回 x / y 的值	x : string , y : string
eq(x, y)	判断 x == y	x : string , y : string
ge(x, y)	判断 x ≥ y	x : string , y : string
gt(x, y)	判断 x > y	x : string , y : string
le(x, y)	判断 x ≤ y	x : string , y : string
lt(x, y)	判断 x < y	x : string , y : string
negate(x)	返回 x 的相反值	x : string
pow(x, y)	返回 x 的 y 次幂	x : string , y : number
quotientRemainderPositive(x, y)	商剩余正数：返回值为一个数组，数组中有两个元素，索引0：x/y的商；索引1：x/y的余数	x : string , y : string
sub(x, y)	返回 x - y 的值	x : string , y : string
subPositive(x, y)	返回 x - y 的值,值必须为正整数	x : string , y : string
sum(...arg)	求所有参数的和	...arg : string
