2. toFixed() Formats a number with a specific number of digits to the right of the decimal. 3. toLocaleString() Returns a string value version of the current number in a format that may vary according to a browser's local settings. 4. toPrecision() Defines how many total digits (...

This function takes in one argument, an optional integer specifying the number of digits after the decimal point. It returns the exponential representation of the number in a string format. Example: toExponential() Copy let myNumber: number = 123456; myNumber.toExponential(); // returns 1.23456...

在C#的数值运算中,有时候需要对计算结果舍去小数位保留整数位向下取整即可,此时就可使用内置方法Math.Floor来实现向下取整操作,Math.Floor方法将舍去小数部分,保留整数.Math.Floor方法有2个重载函数,一个为Math.Floor(double value),另一个为Math.Floor(decimal value),value代表需要向下取整的数值变量. (1)对double...
