	##**Format**## returns a string with the result of the numerical expression formatted as indicated in the formatting expression.
	The formatting expression is a string that can yield numeric or date-time values.

{{fbdoc item="desc"}}
	To recover meaningful date-time values the numerical expression must be a date serial obtained from the appropriate functions.
	This function is part of ""FreeBASIC"", however it is not recognized by the compiler unless ##vbcompat.bi## is included.
