Subject: Re: How to use a float value with either GLYPH_DEBUG or NSTRACE
Date: Mon, 21 Aug 2017 21:30:21 -0700 [thread overview]
Message-ID: <m2pobo442q.wl%esq@lawlist.com> (raw)
Thank you, Paul, for the suggestion to use dtoastr. I tried that and a few variations, but got stuck because dtoastr returns an `int` and `%s` expects a `char` value. Substituting `%s` for `%d` did not yield the correct results.
Keith
