Convert a String to Float
-
i want to read a number from a text file on my hard drive, containing only this number
i wrote this
hcal = IO.read("C;\\...txt").chomp hcal.to_fbut when i check
hcal.classhcal is still a string, not a float...
can you tell me where is my mistake?
-
hcal = IO.read("file.txt").strip.to_f -
hcal.to_fdoesn't modifyhcal, it returns a float. So you need to write it like so:hcal = hcal.to_f -
