Hm, not sure about that, there is a validator in the textCtrl to check
for float values...
[testing]

Ok, if you use 'inf' as a default answer it should work because
float('inf') is a valid expression in Python.
But there was 'infinity', so if you insist on 'infinity', some
conversion must be done in forms.py before setting the value.
