Hello, I need to round the number to an integer value in JavaScript in order to display percentages properly.

What I have tried:

JavaScript
const calc2=((ebitImpactdkk / this.state.ebitBaseline || 0) * 100).toFixed() + '%'; 

I have tried to do that with a toFixed function and was happy, until I have discovered that it converts the number to a string, while I need it still to be a number.

Why? You're immediately appending a string to it, so even if it was still a number, it would be converted to a string at that point.

If you want to round a number to an integer whilst keeping it as a number, use Math.round:

Richard you are right, I guess I can remove the percentage from the input and add it in it's description. But if I change this line to:
const calc2 = (Math.round(ebitImpactdkk / this.state.ebitBaseline ) * 100) || 0;

I am getting either 100, or 0.

Move the * 100 inside the call to round:
const calc2 = Math.round((ebitImpactdkk / this.state.ebitBaseline  || 0) * 100);

Now it works perfectly, thanks!
