Fractions to decimal conversion script wanted
Hello,
I would like for our clients to enter inch lengths in fraction format (i.e. "3/8") such that the output is given in decimal 'mm' format. And - if possible - the script should also be able to work backwards. That's to say: if one were to enter "9.5 mm", the thing should disgorge "3/8". I think, however, that this is pushing it, somewhat.
All mm. values can be rounded off to a single decimal.
Thank you
Here's what I got:
<HTML>
<HEAD>
<TITLE></TITLE>
</HEAD>
<BODY>
<SCRIPT LANGUAGE="JavaScript">
//
var in2mm = true;
function convert(val) {
val = val-0;
// if (in2mm) return (val*25.4) + 'mm'; // in -> mm
// else return (val*0.03934)+'"'; // mm -> in
if (in2mm) return round(val*25.4,5); // in -> mm
else return round(val*0.03934,5); // mm -> in
}
function round(number,X) {
// rounds number to X decimal places, defaults to 2
X = (!X ? 2 : X);
return Math.round(number*Math.pow
}
// --></SCRIPT>
<FORM onSubmit="return false"">
<INPUT SIZE="5" TYPE="text" NAME="from" VALUE="" onChange="this.form.to.val
<BR><INPUT SIZE="5" TYPE="text" NAME="to" VALUE="">

This question was awarded, but never cleared due to the JSP-500 errors of that time. It was "stuck" against userID -1 versus the intended expert whom you awarded. This corrects the problem and the expert will now receive these points; points verified.

if (in2mm) return round(val*25.4,1); // in -> mm
else return round(val*0.03934,1); // mm -> in
1 decimal.
If you can give me a list of valid fractions for the product, I can make a look up table and return a fraction.
I would suggest having both values like this:
[ 9.5mm (3/8") ]
perhaps
