+%description bigdecimal
+Ruby provides built-in support for arbitrary precision integer
+arithmetic. For example:
+
+42**13 -> 1265437718438866624512
+
+BigDecimal provides similar support for very large or very accurate
+floating point numbers. Decimal arithmetic is also useful for general
+calculation, because it provides the correct answers people
+expect–whereas normal binary floating point arithmetic often
+introduces subtle errors because of the conversion between base 10 and
+base 2.
