How do I set up an input (text pattern) for a dollar field

I have a page where I'm getting data from a previous page.  The field is a monthly rental and therefor is #####.##.  The data being passed is "250.00".  I originally had the field as a numeric but that displays "250".  I've tried several different "patterns" that i googled but they didn't work as advertised.

The code that I'm currently running is:

echo '<input type="number" pattern = "0.00-99999.99 {8}" title = "Enter a dollar amount without commas" name="$PSF" size = "8" min = "0.00" max = "99999.99" value="';
echo $work;
echo '" maxlenghth="8" step = "0.01">';

The source code in the browser reads as:

<input type="number" pattern = "0.00-99999.99 {8}" title = "Enter a dollar amount without commas" name="$PSF" size = "8" min = "0.00" max = "99999.99" value="250.00" maxlenghth="8" step = "0.01">

Thanks for the help

Try using type text with a regex pattern

input type="text" pattern="^\d*(\.\d{2}$)?"

Here are some examples of dealing with this problem.

That worked.  But how do I let the user add commas to the field?  Is there a site that I can learn how the "pattern" works?

The pattern in this case is a regular expression or regex and there are lots a good sites with tutorials on this subject eg http://regexone.com/

Here is a regex that allows for currency

^([0-9]{1,3},([0-9]{3},)*[0-9]{3}|[0-9]+)(\.[0-9][0-9])?$
