Re: How to use a float value with either GLYPH_DEBUG or NSTRACE

[Keith David Bershatsky]

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.
