C
Type: Command
Description: Pixel to Complex Command: Converts the specified pixel coordinates to user-unit coordinates.
The user-unit coordinates are derived from the (x
min
, y
min
) and (x
max
, y
max
) parameters in the
reserved variable PPAR. The coordinates correspond to the geometrical center of the pixel.

Q
Type: Command
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.

Qπ
Type: Command
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.
