[How to convert a string to a single in Boo][Need help!!!]

Hi, all!
How can I convert a string to a single in Boo?
I wanna read some parameters from a file, and all parameters are read in as string. I try the cast(single, string) to convert them to single, but it does not work. How can I do the converting?

Thanks a lot!
