branch: master
commit 3064fee41902cf07de4fd612b81b8b5aa904522a
Author: Gregory W. Chicares <gchicares@sbcglobal.net>
Commit: Gregory W. Chicares <gchicares@sbcglobal.net>

    Add a helper function with a deliberately ugly name
    
    This is a handy replacement for dblize() when cents are wanted rather
    than dollars. Occurrences of either dblize() or centize() are suspect,
    and should perhaps be replaced eventually.
