Comma or Period – Which Belongs in the Mortgage Calculator?
Thursday December 4, 2008 at 6:21 pmWe had noticed more of our users getting errors on our Quicken Loans website calculators than we thought there should be. So we took a look. Apparently some people use a period when typing a number greater than or equal to one thousand in place of the comma.
Some people were typing: $200,000
Others were typing: $200.000
Truthfully, they mean two different things, but we’re not here to debate whether a comma or period is correct. We just want to know how to best adapt to our visitors and help them along through our site.
So here’s what we told our engineers:
If a visitor types a period or a comma with three trailing zeroes, go ahead and the punctuation and we’ll take the number as is.
But – if a visitor types a comma or decimal with two trailing zeroes, drop the punctuation and the zeroes and we’ll just use the resulting number.
Might sound complicated, but it really makes a lot of sense. This way, whether you use a comma or period to denote the thousands place or the cents on the dollar, either way, we get it. We understand and we’ll do our best to get you results for your calculations.
Just another way we listen to our users and make their visit to our website just a little more pleasant.
