time.to_f

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 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…
