I'm grabbing a value from a database that returns numbers like 0025 or 0042. It really means 25 and 42. How do I put thos values into a javascript variable while letting it know that its an integer? Javascript doesn't like numbers with double zeros in front of it.  It returning 0025 as 21 for some reason. How do I convert 0025 to 25?

If there are some numbers with decimals, use parseFloat(NumberFromDatabase). If there aren't any decimal numbers, just integers, use: parseInt(NumberFromDatabase) as in the comment above.

You have to put the radix as second parameter of the parseInt() method.
Like this:

var theNum = parseInt("0025", 10);

Oh, the default radix for numbers starting with zero is eight (octal numbers).

Use this one...

function removeLeadZero (z) {
while (z.charAt(0)=="0")
{
z=z.substring(1,z.length);
}

// Case all 0
if (!z.length) { z="0"; }
return z;
}
alert (parseInt(removeLeadZero('0025')));
alert (parseInt(removeLeadZero('0042')));
alert (parseInt(removeLeadZero('000000')));
