How to use Number constructor In Typescript
In this approach, we are using the Number constructor to convert a numeric value to a string with a fixed number of decimal places using the toFixed method, then this constructor is used to the resulting string, which parses it back into a floating-point number with the specified precision.
Syntax:
Number(value: any): number;
Example: The below example uses the Number constructor and toFixed method to convert the number 123.45678 into a string with two decimal places and then parses it back to a floating-point number (123.46).
Javascript
const input: number = 123.45678;const output: number = Number(input.toFixed(2));console.log(output); |
Output:
123.46
