+This Milo Yip DTOA library (emyg_dtoa) is used to avoid issues where the
+standard sprintf() dtoa function changes output based on locale settings. It
+is also 40-50% faster than the standard dtoa for raw numeric data. The use of
+this library is optional. If you wish to use it you can pass
+`USE_DTOA_LIBRARY=1` to make when compiling.
