[PHP2] ECHO Format

Hi, I'm new to the list and to PHP, but this is an old question. I hope some of you have good memories. The isp which hosts the site I am working on only has PHP ver 2 installed. I have a variable $Total which is the sum of various prices. When I display $Total using ECHO I get a lot of extra zeroes. For example, I get 12345.0000000000 instead of 12345.00. How can I format the ECHO command to give me only 2 decimal places? I posted this question on the phpbuilder forum, but the only response I got was to use printf instead of echo. Unfortunately, PHP 2 does not have a printf function. Anyone remember back to PHP 2 and can answer this? Thanks, Jo Ann
