You are probably assigning an empty string to a Float somewhere
What are the types of "automatic" and "IP.Answer", and which is its value when it crashes?

automatic is int variable
the imput is forced to decimal number
in my device everthing works even if i enter numbers like 122.4
it seems that the errorr does not repeat ..so how knows
