Unary-op-double

Change-unary-op-double

Modifying constructor for unary-op-double structures.

Syntax

(change-unary-op-double x 
                        )

This is an often useful alternative to make-unary-op-double.

We construct a new unary-op-double 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
