Does mORMOt have a better way for checking if str can be converted num

I know I can use TryStrToFloat, but is there any other (better, and faster) way provided by mORMot,  to check if a string can be converted to number?

GetExtended() or GetInteger() or GetInt64() have overloaded versions which returns an error integer index, which is 0 if the UTF-8 text is a number.

You also have some other functions in the variants part of the framework, if you need to identify if some text is integer/currency/double or something else.
