HP 48gII Graphing, 50g Graphing manual Px→C, →Qπ, + c/d*i

PX→C

Type:	Command
Description:	Pixel to Complex Command: Converts the specified pixel coordinates to userunit coordinates.
	The userunit coordinates are derived from the ( xmin, ymin) and (xmax, ymax) parameters in the
	reserved variable PPAR. The coordinates correspond to the geometrical center of the pixel.
Access:	!°LPICT LPX→C		( °is the leftshift of the	Nkey).
Input/Output:
		Level 1/Argument 1		Level 1/Item 1
		{ #n #m }	→	(x,y)
See also:	C→PX
→Q	Command
Type:
Description:	To Quotient Command: Returns a rational form of the argument.

The rational result is a “best guess”, since there might be more than one rational expression consistent with the argument. →Q finds a quotient of integers that agrees with the argument to within the number of decimal places specified by the display format mode.

→Q also acts on numbers that are part of algebraic expressions or equations. Access: „Ú REWRITE L→Q (Ú is the leftshift of the 6key).

Flags:	Number Display Format (–45 to –50)
Input/Output:
		Level 1/Argument 1		Level 1/Item 1
		x	→	'a/b'
		(x,y)	→	'a/b + c/d*i'
		'symb1'	→	'symb2'
Example:	'Y+2.5'	→Q returns 'Y+5/2'

→Qπ	Command
Type:
Description:	To Quotient Times π Command: Returns a rational form of the argument, or a rational form of
	the argument with π, square roots, natural logs, and exponentials factored out, whichever yields
	the smaller denominator.
	The rational result is a “best guess”, since there might be more than one rational expression
	consistent with the argument. →Qπ finds a quotient of integers that agrees with the argument to
	the number of decimal places specified by the display format mode.
	→Qπ also acts on numbers that are part of algebraic expressions or equations.
	For a complex argument, the real or imaginary part (or both) can have π as a factor.
Access:	„Ú REWRITE L →Qπ		(Ú is the leftshift of the 6key).
