+    /// point value back that you encoded.  This format is arbitrary precision
+    /// and not dependant on platform or hardware.
+    ///
+    /// Although the format is arbitrary precision, the backend in C# uses a
+    /// double for maximum precision without resorting to a software arbitrary
+    /// precision library.
+    ///
+    /// Interestingly, unlike many other languages, C# provides a decimal type
+    /// that is also floating point, however the decimal type is encoded using
+    /// a bcd-like scheme.  This makes it an excellent choice for many human
+    /// activities, but it cannot be encoded precisely as a GatsFloat.  If you
+    /// would like to preserve the decimal nature of those types it may be
+    /// better to encode them as strings.
+    ///
+    /// In encoding, the GATS float uses two different type specifiers, an 'f'
+    /// indicates a normal floating point value.  An 'F' represents a special
+    /// value: positive or negative NaN, infinity, or zero.
