toBigDecimal: Avoid creating new BigDecimal instance for some values

Browse Source 
Avoid creating new `BigDecimal` instance by calling `BigDecimal.valueOf(this)`, which doesn't create a new instance if the argument falls in the range [0..10].
(there's a `private static final BigDecimal[] zeroThroughTen` cache in BigDecimal.java with 11 BigDecimal instances)
