Hi everyone!

I’m looking at the following code:

total=total+time\_in[“time”].to\_f

What exactly is to\_f because I cannot find it in the API?

Thanks,

Gabor

Sry, if you go to the [ruby-doc.org](http://ruby-doc.org) site and click on the programm ruby  
reference… press ctrl+f and look for to\_f. I clicked on the first link  
which was for BigNum… it also converts other data types…
