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). |

Type: |
|
|
|
| ||
Description: | Permutations Function: Returns the number of possible permutations of n items taken m at a | |||||
| time. |
|
|

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