Description

This should be simple to add, since decimals can already be parsed from strings. Decimals will be represented in JSON as strings. If a decimal with different precision or scale is parsed from the string, should there be any acceptable conversions? (for example, if the column is of type decimal(5, 2) should "12.3" be an error or equivalent to "012.30"?)
