My code:
$(document).ready(function() {
var num1 = 1473.735;
var num2 = 1473;
var num3 = num1 - num2;
alert(num3); // 0.7349999999999
}
Javascript seems to round my numbers very strangely.
How is it possible that javascript comes up with a strange decimal notation with such a simple calculation?
1473.735 - 1473 = 0.735, and not 0.7349999999999.
Here my Sandbox example: https://codepen.io/thomasveld/pen/yLebMMo
thanks in advance.

Incorrect results in calculations with decimal values with four digits after dot [duplicate]

I have a JavaScript function that returns the result of multiplications using decimal values (four digits after dot).
But, in some conditions, the result is a mess like this:
3.9050 * 9 = 35.144999999999996.
What should I do to normalize those results?

Use .toFixed(numberOfDecsYouWant)
var num = 3.9050 * 9;
console.log(num); //35.144999999999996
console.log(num.toFixed(4)) //35.1450

I am performing a basic calculation using javascript and when I use this combination of number it won't calculate correctly:
alert((40071.13 + 6028.91) - 46100.04);
It should calculate to 0 but it doesn't. All other number combinations work for me.
Help!

This is a rounding issue. Try this to round to 2 decimal places
var num = (40071.13 + 6028.91) - 46100.04;
alert(num.toFixed(2));

I've got the following problem when i'm counting in javascript.
var processAmount = parseFloat(166.98) - parseFloat(61.58);
The result is: 105.39999999999999
Doesnt matter if I use parseFloat() or not.
How can I solve this?

Sometimes floats numbers cannot be represented exactly in binary.
Try this:
var processAmount = parseFloat(166.98) - parseFloat(61.58);
processAmount.toFixed(2);
