## Converting Decimals To Fractions?

Jul 18, 2009

I know this is a rather odd post but I need to be able to convert a decimal to a fraction.Really all i need to know to get what i have to work is being able to tell if a number is whole or not. For instance if i have an accuracy set of .0625 = 1/16"If i take my variable which is set to .5625 (9/16")so if i take variable/accuracy in this case would equal 9. So this way i would know that the numerator would be 9 and my denominator would be 16.If i take the same accuracy of 1/16 and now introduce a variable of 0.5 then it will give me a remainder.

## Search A String For Decimals.

Jul 26, 2005

this function is supposed to search a string for decimals and tell me how many of them it has found, but for some reason, it's not doing it right. since the "period" character is a special character in regular expressions,I went ahead and escaped it, but it's still doesn't work.

function ImprovedFormatAmount(ElementId)
{
var oElement = document.getElementById(ElementId);
var ElementValue = oElement.value;
var DecimalRegXp = /./g;
var OutputValue = ElementValue;
if (OutputValue.length > 0)
}

## Allows ONLY Decimals To Be Typed Into A Text Field

Apr 11, 2011

I have a script that allows ONLY numbers to be typed into a text field. I have tried to modify this script to allow Decimals (periods) to be typed as well, but haven't succeeded. The code in Red are the changes I added to this script, but it isn't working out.

function numbersOnly(evt) {
var charCode = (evt.which) ? evt.which : event.keyCode
if (charCode > 31 && (charCode < 48 || charCode > 57) && (charCode < 110 || charCode > 110))
return false;
return true;
}

Second Problem: I need to set a Minimum number users may type in the text field. Normally this would be a simple task, but the minimum number they may type is a decimal (0.10). The default value in the field is .50. I tried replacing the .50 with .09, and I can't get the field to run the script and set its new value to .10 (<- this is the minimum). Here is the code I am working with.

## Create Random Number Between 1 - 50 With Decimals?

May 24, 2011

How would I go about creating a random number between 1-50 that COULD include whole numbers, decimals to the tenth, hundredth and the thousandth place?
Ex) 2.145, 3, 5.8, 41.002, 10.12, 7, 18.023, 33.2

Also, if the only way to do it is to put trailing zeros to the thousandth place that's fine as well
Ex) 2.145, 3.00, 5.800, 41.002, 10.120, 7.00, 18.023, 33.200

## Formatting Auto-computed OnChange Field To 3 Decimals?

Dec 13, 2010

I have some fields on my form that are auto-populating with a difference from 2 input fields using onChange, easy stuff. The correct value is stored in the DB, to 3 decimal places (correct, since data type is a float with 3 decimals).The challenge I am having is to get the number that is auto-displaying on the form to format to 3 decimals. For example, when I enter the first number at 44.8, and a second number of 44.666, the onChange command displays '0.13400000000000034'. This is saved in the db correctly as, '0.134' and once the form is submitted the correct value of 0.134 displays since it is pulling directly from the db. I would like to format the onChange display with the toFixed command so the extra decimals don't show onChange.

## Round Up 2 Decimal Places

Nov 17, 2011

I am trying to use the following javascript [URL] to create something similar to the example on [URL] for a school project but I wondered if someone could advise me how I can round numbers to 2 decimal places in the field box as I have to convert the calculated value by an exchange rate, e.g.:

where x=100 and y=50
calculate="(x+y)/1.55"

returns a value of 96.77419355. I would like to round this figure up to 2 decimal places so it would read 96.77 but I cannot figure out how to do this.

## Percentages - How To Round Output To Nearest 10s Place

Oct 21, 2009

I'm a bit confused as I'm just learning PHP/Java, and need to display a percentage. I successfully can display a percentage, however, the decimal like any calculate displays .00000012130 whatever sometimes. How can I round the output to the nearest 10s place?
<script language="javascript" type="text/javascript">
var a = "14";
var b = "25";
document.write(parseInt(a) / parseInt(b) * 100);
document.write("%");
</script>
This is the code I use, however, it needs to be modified so that it rounds to the nearest 10 instead of display a decimal.

## Find Request Round Trip Time?

Jun 1, 2011

I was wondering if there is a way to find the total round trip time of a request. Addins like firebug and chromes console show you this round trip time but i was hoping there was a way to extract it from the response itself.

I would also like to know the response time from when the server sent the request and the client received it. I do not think this is possible since the server and client have different timing systems but it would be very useful.
