+# FltUsedLib
+
+This library provides a global (fltused) that needs to be defined anywhere floating point operations are used.
+The C compiler produces the _fltused symbol by default, this is just to satisfy the linker.
+
+## Using
+
+To use FltUsedLib, just include it in the INF of the module that uses floating point.
+
