I would attack the problem thusly:
Upon application startup, record the locale-specific decimal separator
variable into a global variable named UIDecimalSeparator.
Create wrappers for FloatToStr and StrToFloat thusly:
FloatToDataStr
(change DecimalSeparator to '.' then call FloatToStr)
FloatToUIStr
(change DecimalSeparator to UIDecimalSeparator then call FloatToStr)
DataStrToFloat
(change DecimalSeparator to '.' then call StrToFloat)
UIStrToFloat
(change DecimalSeparator to UIDecimalSeparator then call StrToFloat)
Now you code can use FloatToDataStr / DataStrToFloat for file I/O, and
FloatToUIStr / UIStrToFloat for UI purposes.
Similar wrappers for DateToStr / StrToDate can be made.
