CENTR

Command

 

 

 

Type:

 

 

 

Description:

Center Command: Adjusts the first two parameters in the reserved variable PPAR, (xmin, ymin) and

 

(xmax, ymax), so that the point represented by the argument (x, y) is the plot center. On the HP 50g

 

and 49g+, the center pixel is in row 40, column 65 when PICT is its default size (131 × 80). On

 

the 48gII, the center pixel is in row 32, column 65 when PICT is its default size (131 × 64).

 

If the argument is a real number x, CENTR makes the point (x,0) the plot center.

%CH

Function

 

 

 

Type:

 

 

 

Description:

Percent Change Function: Returns the percent change from x to y as a percentage of x.

 

If both arguments are unit objects, the units must be consistent with each other. The dimensions

 

of a unit object are dropped from the result, but units are part of the calculation.
