Fconst-hex

Change-fconst-hex

Modifying constructor for fconst-hex structures.

Syntax

(change-fconst-hex x 
                   [:prefix <prefix>] 
                   [:core <core>] 
                   [:suffix? <suffix?>])

This is an often useful alternative to make-fconst-hex.

We construct a new fconst-hex 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

This is an ordinary change- macro introduced by fty::defprod.

                           (:suffix? . fconst-hex->suffix?))
