PDIM

Command

 

 

 

Type:

 

 

 

Description:

PICT Dimension Command: Replaces PICT with a blank PICT of the specified dimensions.

 

If the arguments are complex numbers, PDIM changes the size of PICT and makes the arguments

 

the new values of (xmin, ymin) and (xmax, ymax) in the reserved variable PPAR. Thus, the scale of a

 

subsequent plot is not changed. If the arguments are binary integers, PPAR remains unchanged,

 

so the scale of a subsequent plot is changed.

 

 

 

PICT cannot be smaller than 131 pixels wide × 80 pixels high on the HP 50g and 49g+ (64 pixels

 

high on the HP 48gII) nor wider than 2048 pixels (height is unlimited).

PERM

Function

 

 

 

 

Type:

 

 

 

 

Description:

Permutations Function: Returns the number of possible permutations of n items taken m at a

 

time.

 

 

 

 

 

The formula used to calculate Pn,m is:

 

 

 

 

 

 

Pn, m =

n!

 

 

 

 

 

(-------------------nm)!

 

 

 

The arguments n and m must each be less than 1012. If n < m, zero is returned.
