From fcdb2df009796a78369a7fe8bcaab76b27f5450b Mon Sep 17 00:00:00 2001 From: Tom Sepez Date: Fri, 31 Mar 2017 10:32:07 -0700 Subject: Re-arrange fxcrt string files to match naming. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The top-level fx_string.h is kept to include all strings. Put all fx_atof code in fx_basic_util.cpp rather than header.
