 A short and concise JavaScript library for the four fundamental operations of arithmetic, which supports the addition, subtraction, multiplication and division calculation of floating-point precision.
 
-提供常见的加(`add`)、减(`sub`)、乘(`mul`)、除(`div`)计算方法，可满足涉及金额、价格处理等前端数据计算的大多数应用场景。
-
 ## Features
 
 - Short and sharp. It only includes the calculation of addition, subtraction, multiplication and division. The core code is less than 100 lines. There is no other dependency.
