simple question, calculation with numbers...

[commun1]

I habe some vars containing numbers which look like this.

$number1 = 1.10

when I echo this var I get 1.1 as a result, so the last 0 is been dumped. I need the 0 to be stored too though, for further calculations and so that it is printed as 1.10

how do I achieve that? can you give me an example?
I suppose I'd need floating numbers but how do I tell the script that I only need 2 digits after the preceding point?

Hi,
use printf() function:

$var = 1.1;
printf ("%.2f", $var);

that means: print a float with 2 digits after ".".

For example if you want "0001.100", you could use:
printf ("%04.3f", $var);
