When typing in "-" into decimal field nothing happens; when typing "-" into number field there is a message "Unacceptable character: you can type only number here". But both fields can accept minus sign if the value is copy-pasted into them. Just in case I checked if the keyboard gives the right character, it was a correct one: chr(45).
Build 3731.
UPDATE: Same issue with "."
