+  \brief Classify floating-point value as normal, subnormal, zero, infinite, or NaN.
+  \version 1.0
+  \author John Maddock
+ */
+
+/*
+
+1. If the platform is C99 compliant, then the native floating point
+classification functions are used.  However, note that we must only
+define the functions which call std::fpclassify etc if that function
+really does exist: otherwise a compiler may reject the code even though
+the template is never instantiated.
+
+2. If the platform is not C99 compliant, and the binary format for
+a floating point type (float, double or long double) can be determined
+at compile time, then the following algorithm is used:
+
+        If all exponent bits, the flag bit (if there is one),
+        and all significand bits are 0, then the number is zero.
+
+        If all exponent bits and the flag bit (if there is one) are 0,
+        and at least one significand bit is 1, then the number is subnormal.
+
+        If all exponent bits are 1 and all significand bits are 0,
+        then the number is infinity.
+
+        If all exponent bits are 1 and at least one significand bit is 1,
+        then the number is a not-a-number.
+
+        Otherwise the number is normal.
+
+        This algorithm works for the IEEE 754 representation,
+        and also for several non IEEE 754 formats.
+
+    Most formats have the structure
+        sign bit + exponent bits + significand bits.
+
+    A few have the structure
+        sign bit + exponent bits + flag bit + significand bits.
+    The flag bit is 0 for zero and subnormal numbers,
+        and 1 for normal numbers and NaN.
+        It is 0 (Motorola 68K) or 1 (Intel) for infinity.
+
+    To get the bits, the four or eight most significant bytes are copied
+    into an uint32_t or uint64_t and bit masks are applied.
+    This covers all the exponent bits and the flag bit (if there is one),
+    but not always all the significand bits.
+    Some of the functions below have two implementations,
+    depending on whether all the significand bits are copied or not.
+
+3. If the platform is not C99 compliant, and the binary format for
+a floating point type (float, double or long double) can not be determined
+at compile time, then comparison with std::numeric_limits values
+is used.
