+ * otherwise that the non-significant bits should be simply disregarded and the range of values are
+ * calculated as the numeric interval obtained by varying the range of "insignificant bits" between
+ * its extremes. As a simple example, consider the value 33 as a simple 8-bit number with three
+ * significant bits: 33 is 00100001 binary and the leading 001 are the significant bits. With the
+ * above definition, the range of numbers are [32,63] with 33 asymmetrically located at the low end
+ * of the interval. In a more realistic setting an instrument, such as a GPS, would most likely
+ * deliver measurements with a gaussian distribution around the exact value, meaning it is more
+ * reasonable to assume the value as a "center" value with a symmetric uncertainty interval.
+ * RFC-6225 redefines the "resolution" from RFC-3825 with an "uncertainty" value with these
+ * properties, which is also the definition suggested here.
+ * </p>
+ * <p/>
+ * <p>
+ * The res fields provides the resolution as the exponent to a power of two,
+ * e.g. 8 means 2^8 = +/- 256, 0 means 2^0 = +/- 1 and -7 means 2^-7 +/- 0.00781250.
+ * Unknown resolution is indicated by not setting the respective resolution field in the RealValue.
