fixed the warning "inline function ‘fpconv_init’ declared but never defined" from gcc.

Use internal dtoa/strtod for double conversion

2012-03-04T08:24:34+00:00

The internal Lua CJSON dtoa/strtod routines have locale support disabled. This avoids problems under locales with comma decimal separators. Build changes: - CMake: Check for big endian architectures - Makefile: Provide option to build with dtoa.c Modifications to dtoa.c: - Include locale dtoa_config.h configuration - Rename Infinity/NaN to inf/nan to match common C libraries - Rename strtod() -> internal_strtod() to prevent conflict with libc function Modifications to g_fmt.c: - Return output string length (instead of original buffer pointer) - Provide precision as an argument to g_fmt() - Silence compilations warnings from vendor source - while(a = b) - Unused label "done:" - Only swap to scientific notation when once the number of decimal digits required exceeds the precision available. This matches standard printf format %g. - Display a "0" in front of numbers < 1.

Sanitise locale code, comments and documentation

Add fpconv to work around comma decimal points

2011-12-30T03:47:44+00:00

Create a separate buffer and translate comma <> dot before calling strtod(), and after calling sprintf() as required. - Add "update_locale" Lua API call and init locale on module load. - Move sprintf format string to fpconv
