js 加减乘除 方法

基于 big.js 封装的 加减乘除 方法

import Big, { BigSource } from 'big.js';/** 加法函数 */
export function add(num1: BigSource, num2: BigSource, decimal: number = 2): string {return Big(num1).plus(Big(num2)).toFixed(decimal);
}/** 减法函数 */
export function subtract(num1: BigSource, num2: BigSource, decimal: number = 2): string {return Big(num1).minus(Big(num2)).toFixed(decimal);
}/** 乘法函数 */
export function multiply(num1: BigSource, num2: BigSource, decimal: number = 2): string {return Big(num1).times(Big(num2)).toFixed(decimal);
}/** 除法函数 */
export function divide(num1: BigSource, num2: BigSource, decimal: number = 2): string {return Big(num1).div(Big(num2)).toFixed(decimal);
}
