Enhancements to the DECIMAL extension:
...
(1) If the argument to decimal(X) is a floating point value (or an 8-byte blob),
the floating point value is expanded into its exact decimal representation.
(2) Function decimal_sci(X) works the same except it returns the result in
scientific notation.
(3) New function decimal_pow2(N) returns the full decimal expansion of the N-th
integer power of 2.
