Jquery - .toFixed(2) fixed number reduce to 3 digits

Question

I have the following code that works with the exception of limiting the #result2 to 3 digits

current #result2: input 1 and you get 0.010416666666666666

needed #result2: input 1 and get 0.01

I need to limit the result to 0.00 2 digits after so that it is not a long result.

This is going to be used to convert pixels to inches for designers as part of a pet project.

** What would be really great is if the result would actually convert to inches, example: input 1 and get back 1/8 but not sure if that can be done???

Here is the Html:

<label>Pixels</label>
<input class="calcd" id="calc3" type="text" />
<input class="calcd" id="calc4" type="hidden" value="96" />
<p>Inches</p><span id="result2"></span>

Here is the Jquery:

$(document).ready(function(){

    $(".calcd").keyup(function(){

        var val1 = parseInt($("#calc3").val());
        var val2 = parseInt($("#calc4").val());

        if ( ! isNaN(val1) && ! isNaN(val2))
        {
             $("#result2").text(val1 / val2).toFixed(3);
        }
    });

});

Thanks in advance!

Answer 1

$("#result2").text(val1 / val2).toFixed(3);

There's your problem. You want to call toFixed(3) on the value before you pass it to text().

$("#result2").text((val1 / val2).toFixed(3));

It may be useful to step through with a debugger at times like this, to see where expressions are evaluated and how it works.
