		Value to find the absolute value of.

{{fbdoc item="ret"}}
	The absolute value of ##//number//##.

{{fbdoc item="desc"}}
	The absolute value of a number is its positive magnitude.  If a number is negative, its value will be negated and the positive result returned.  For example, ##Abs(-1)## and ##Abs(1)## both return ##1##. The required ##//number//## argument can be any valid numeric expression.
	Unsigned numbers will be treated as if they were signed, i.e. if the highest bit is set the number will be treated as negative, and its value negated.
	The value returned will be greater than or equal to ##0##, with the exception of signed integers containing the lowest possible negative value that can be stored in its type, in which case negating it will overflow the result.

	The ##**Abs**## unary ##[[KeyPgOperator operator]]## can be overloaded with user defined types.
