[jira] [Created] (CALCITE-5999) DECIMAL literals as sometimes unparsed looking as DOUBLE literals

Mihai Budiu created CALCITE-5999:
------------------------------------

             Summary: DECIMAL literals as sometimes unparsed looking as DOUBLE literals
                 Key: CALCITE-5999
                 URL: https://issues.apache.org/jira/browse/CALCITE-5999
             Project: Calcite
          Issue Type: Bug
          Components: core
    Affects Versions: 1.35.0
            Reporter: Mihai Budiu


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.
