Encodes `decimal.Decimal`

instances.

There are several ways in which a decimal value might be encoded.

Special values are encoded as special strings:

- Positive infinity is encoded as C{"Infinity"} - Negative infinity is encoded as C{"-Infinity"} - Quiet not-a-number is encoded as either C{"NaN"} or C{"-NaN"} - Signalling not-a-number is encoded as either C{"sNaN"} or C{"-sNaN"}

Normal values are encoded using the base ten string representation, using engineering notation to indicate magnitude without precision, and "normal" digits to indicate precision. For example:

- C{"1"} represents the value I{1} with precision to one place. - C{"-1"} represents the value I{-1} with precision to one place. - C{"1.0"} represents the value I{1} with precision to two places. - C{"10"} represents the value I{10} with precision to two places. - C{"1E+2"} represents the value I{10} with precision to one place. - C{"1E-1"} represents the value I{0.1} with precision to one place. - C{"1.5E+2"} represents the value I{15} with precision to two places.
