[RESOLVED] addition

[slimjim]

I have to variables that are like this :

$var1=2.00;
$var2=2.00;

Now when i do this to add i lose the decimal

$var3=$var1+$var2;

I get 4 and I want to get 4.00

What am i doing wrong..

In math 4 is equal to 4.00 (if we do not account for significant numbers as used in science). So if you want 4 to be 4.00 it is just a matter of proper formatting.

Try this:

echo number_format($var3, 2);
