+// The numeric_limits<> traits document implementation-defined aspects
+// of fundamental arithmetic data types (integers and floating points).
+// From Standard C++ point of view, there are 13 such types:
+// * integers
+// bool (1)
+// char, signed char, unsigned char (3)
+// short, unsigned short (2)
+// int, unsigned (2)
+// long, unsigned long (2)
+//
+// * floating points
+// float (1)
+// double (1)
+// long double (1)
+//
+// GNU C++ understands (where supported by the host C-library)
+// * integer
+// long long, unsigned long long (2)
+//
+// which brings us to 15 fundamental arithmetic data types in GNU C++.
+//
+//
+// Since a numeric_limits<> is a bit tricky to get right, we rely on
+// an interface composed of macros which should be defined in config/os
+// or config/cpu when they differ from the generic (read arbitrary)
+// definitions given here.
+//
+
+// These values can be overridden in the target configuration file.
+// The default values are appropriate for many 32-bit targets.
+
+// GCC only intrinsically supports modulo integral types. The only remaining
+// integral exceptional values is division by zero. Only targets that do not
+// signal division by zero in some "hard to ignore" way should use false.
