###Remarks###
A string is a float if it contains at least one decimal digit and exactly one period; the only other character allowed is an optional plus or minus at the beginning.  (StringIsFloat does not accept a comma character as the decimal point even if the computer Locale settings use that symbol.)  If parameter is not a string, its value is converted to a string.
