The toFixed() method converts a number to a string. The toFixed() method rounds the string to a specified number of decimals.
In JavaScript, toFixed() is a Number method that is used to convert a number to fixed-point notation (rounding the result where necessary) and return its value as a string. Because toFixed() is a method of the Number object, it must be invoked through a particular instance of the Number class.
The "toFixed is not a function" error occurs when the toFixed() method is called on a value that is not a number . To solve the error, either convert the value to a number before calling the toFixed method or only call the method on numbers.
The method toFixed(n) rounds the number to n digits after the point and returns a string representation of the result. We can convert it to a number using the unary plus or a Number() call, e.g write +num. toFixed(5) .
Use the various String.Format() patterns.
For example:
int someNumber = 20; string strNumber = someNumber.ToString("N2"); Would produce 20.00. (2 decimal places because N2 was specified).
Standard Numeric Format Strings gives a lot of information on the various format strings for numbers, along with some examples.

You could make an extension method like this:
using System; namespace toFixedExample { public static class MyExtensionMethods { public static string toFixed(this double number, uint decimals) { return number.ToString("N" + decimals); } } class Program { static void Main(string[] args) { double d = 465.974; var a = d.toFixed(2); var b = d.toFixed(4); var c = d.toFixed(10); } } } will result in: a: "465.97", b: "465.9740", c: "465.9740000000"
