	@keyterms:
		lcdnumber object class, lcd
	@title:
		lcdnumber class
	@type:
		class
	@short:
		The lcdNumber widget displays a number with LCD-like digits.
	@inherits:

	@description:
		It can display a number in just about any size. It can display decimal,
		hexadecimal, octal or binary numbers.
	@functions:
		!fn: $displayStr(<number:string>)
		Displays the number represented by the string s.
		!fn: $displayInt(<number:integer>)
		Sets the displayed value rounded to the nearest integer to number.
		!fn: $displayDouble(<number:double>)
		Sets the displayed value to number (double).
		!fn: $setMode(<mode:string>)
		Sets the current display mode (number base): valid mode are HEX,BIN,OCT,DEC.
		!fn: $setSegmentStyles(<style:string>)
		Sets the style of the lcdnumber, valid styles are: Outline,Filled,Flat.
		!fn: $setNumDigits(<number:integer>)
		Sets the lcd number value.
		!fn: <boolean> $checkOverflow()
		Returns TRUE if num is too big to be displayed in its entirety;
		otherwise returns FALSE.
		!fn: $setSmallDecimalPoint(<bflag:boolean>)
		Sets the the decimal point style, valid bool values are 1 or 0.
		!fn: <boolean> $checkOverflow(<number:integer>)
		Returns 1 (TRUE) if num is too big to be displayed in its entirety; otherwise returns 0 (FALSE).
