Display values in decimal places

I am trying to display Cash Return in two decimal places. I tried using .toFixed however, it's not working. I am trying to display 1 million as 1.00 or 10 million as 10.00 and so forth but always in 2 decimal place.

What I have tried:

var Return = document.getElementById("Cash").value;
var CashRate = document.getElementById("CashRate").value;

aCashReturnCompensation = (Return/1000000);

CashRate =   Math.pow(1+CashRate/100,1/365)-1;
document.getElementById("CashReturn").value=Math.floor(Return/Math.pow(1+CashRate,periods);

Example:

var number = 55.4301;

to reduce the precision ... use:

number.toPrecision(2)

which will give you:

55.43

A bit of a warning for your future coding.

Although, in javaScript it doesn't matter, there is a difference as to how calculations will end up if you use 1000000 and not 1000000.0 - in how they are stored, which number is first in a calculation if you mix types, and any number of other rules for a language implementation.

Round off errors during calculations could give you unexpected results.

Thank you. I will keep that in mind.

"It's not working" is not a helpful description of the problem.

Gazing into my crystal ball, I'm guess that CashReturn is an <input type="number" />.

Furthermore, I'm guessing that you're using Firefox, which unfortunately doesn't support fixed decimals in numeric inputs at the moment. There's a bug report[^] for this, but it's been open for 4 years with no sign of a resolution.

(If that's not the problem, then you need to update your question to provide a proper description of the problem.)

This worked for me.

/1000000).toFixed(2);
