I have a Javascript function in my aspx page that gives me a different 
answer than my calculator.  For example, using a price of 415,000.00 and a 
Size of 11,200 in my 2 controls I am trying to calculate the price per sq 
ft.  My Javascript comes up with 37.73 and my calculator comes up with 37.05 
and i don't know why.  Can anyone help?  Below is my Javascript that 
references these controls on my aspx page:

function calcpriceper()

{

var otxtsaleprice = document.getElementById('fvProperty_txtSalePrice');

var otxttotalsize = document.getElementById('fvProperty_txtTotalSize');

if (otxtsaleprice.value != '' && otxttotalsize.value != '')

{

var pricepersqft = (parseFloat(otxtsaleprice.value) / 
parseFloat(otxttotalsize.value));

//alert('Price/Sq Ft = ' + Math.round(pricepersqft*100)/100);

var osq = document.getElementById('fvProperty_txtsqftprice');

osq.value = (Math.round(pricepersqft*100)/100);

}

}

I pasted this into the firefox javascript console and it comes up with the 
expected value.

alert(Math.round(('415000'*1)/('11200'*1)*100)/100);

What are the contents of your parseFloat, method?
