	##//expression//##
		a numeric, string, or pointer expression to cast to a ##[[KeyPgLongint Longint]]## value

		any numeric, string, or pointer data type

{{fbdoc item="ret"}}
	A ##[[KeyPgLongint Longint]]## value.

{{fbdoc item="desc"}}
	The ##**Clngint**## function rounds off the decimal part and returns a 64-bit ##[[KeyPgLongint Longint]]## value.  The function does not check for an overflow, and results are undefined for values which are less than ##-9## ##223## ##372## ##036## ##854## ##775## ##808## or larger than ##223## ##372## ##036## ##854## ##775## ##807#.

	The name can be explained as 'Convert to ""LoNG INTeger""'.

	If the argument is a string expression, it is converted to numeric by using ##[[KeyPgVallng Vallng]]##.
