Javascript's ParseFloat function returns a string instead of a number

I have an array retrieved from an API that looks like this:

x = [0, 12.1, 23.45, 100.23, 13.99, 90, 0, 16.1]

I need each number to have a decimal point up to two places, such as 0.00 or 12.10.

Here is what I tried:

x = x.toFixed(x);

However, this converts the values to strings instead of numbers. I am unsure how to keep them as numbers after converting them to decimals.

Someone suggested this code, but it did not work for me:

x = +x.toFixed(2);

I also attempted using parseFloat after toFixed, but although the console shows it as a number, it is actually still a string.

I am attempting to do this within an Angular 2+ application in a PrimeNG table.

Answer №1

Utilizing the pipe function on the HTML side is recommended

{{x | number:'1.1-3'}}

For more information, please visit: https://angular.io/api/common/DecimalPipe#example

Note: Make sure to include DecimalPipe in your declarations

If you need to implement this on the TypeScript side, the provided solution should suffice

(15).toFixed(2) //15.00
