TypeScript Equivalent

Question

Using the below code in Angular to cast the number to 2 decimal places using DecimalPipe.

constructor(private decimalPipe: DecimalPipe) {}

this.decimalPipe.transform('0','.2-2') //output 0.00

Any ideas of theTypeScript equivalent?

toPrecision(2) doesn't works the same

e.g.

var num = 2;

2.toPrecision(2)

Expected: 2.00 Actual: 2.0

You can use javascript function toFixed(2);

If you want to round, you can use (Math.round(num * 100) / 100).toFixed(2);

var a = 2; a.toFixed(2) return your expectation 2.00 – Hien Nguyen Apr 22 '20 at 15:00
Why do you need to use Math.round? `toFixed` rounds a value by default. `(1.999).toFixed(2) // 2.00` – Eugene Karataev Apr 22 '20 at 16:56
