Pnumber-dot-digit

Change-pnumber-dot-digit

Modifying constructor for pnumber-dot-digit structures.

Syntax

(change-pnumber-dot-digit x 
                          [:digit <digit>])

This is an often useful alternative to make-pnumber-dot-digit.

We construct a new pnumber-dot-digit structure that is a copy of x, except that you can explicitly change some particular fields. Any fields you don't mention just keep their values from x.

Definition
