Pnumber-number-upcase-e-sign

Change-pnumber-number-upcase-e-sign

Modifying constructor for pnumber-number-upcase-e-sign structures.

Syntax

(change-pnumber-number-upcase-e-sign x 
                                     [:number <number>] 
                                     [:sign <sign>])

This is an often useful alternative to make-pnumber-number-upcase-e-sign.

We construct a new pnumber-number-upcase-e-sign 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.
