[Resolved] echo double vs int

[nikko50]

Hello all,
If I have a variable called $num=22;
How can I echo that as a double like 22.00?

I tried the below but no luck.

$num= settype($num,"double");
echo $num;

Thanks for the help. Came up with this...

echo $num = sprintf("%01.2f", $num);

Let's say I have the sample below, how can I have the commas print $num=11,122.22;

$num=11122.22;
echo $num = sprintf("%01.2f", $num);
