I have the following problem with IE when making calculations with floating-point numbers.

For instance, I have a div, which width is 150px and length 150px. I am subtracting say 15.78775456545464 from its width.

Code:
div.style.width = (parseFloat(div.style.width) - 15.78775456545464) + "px";
All major browsers return 134.21224543454537 px, but IE returns 134.21. Internet Explorer removes all the decimals, but the first TWO.

I'm using IE 10.

Is there a way to return all decimals in IE?
