I want to convert floating point to strings and output them into the
HTML file. Round to two after the decimal point.
From php.net, it looks like this is the right way:
$a=2.123456789;
echo sprintf('%f5.2',$a);
I get
2.1234575
So,
1. How do I get 2.12
2. Where does that final 5 come from? I'm guessing the 6 gets rounded up
to 7, but the 5?
Help?
TIA,
Sandy
