Description

Consider a DECIMAL literal such as "0.00000000000000001"

When unparsed this will show up as 1E-17, which is interpreted by SQL as a double literal.

The bug is in the function SqlNumericLiteral.toValue(). The function calls toString() on a BigDecimal value, but it should probably call toPlainString() instead.
