Can an array contain floats?

[larkf]

This seems very basic, but if I enter

$arr[1] = 3.643; 
echo $arr[1];

I get just 3, not the entire number. Can arrays not contain floats or do I have to specially define something?

Thanks!

Thanks so much for the quick response. I'm a dork. I was using a variable name that was used elsewhere in the code. Duh. It's working fine now.
