Sinteger-format

Change-sinteger-format

Modifying constructor for sinteger-format structures.

Syntax

(change-sinteger-format x 
                        [:bits <bits>] 
                        [:signed <signed>] 
                        [:traps <traps>])

This is an often useful alternative to make-sinteger-format.

We construct a new sinteger-format 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
