Julian Hyde updated CALCITE-280:
--------------------------------
Summary: BigDecimal underflow (was: avg() on BigDecimal may cause
java.lang.ArithmeticException: Non-terminating decimal expansion; no exact
representable decimal result.)
> BigDecimal underflow
> --------------------
>
> Key: CALCITE-280
> URL: https://issues.apache.org/jira/browse/CALCITE-280
> Project: Calcite
> Issue Type: Bug
> Reporter: GitHub Import
> Labels: github-import
>
> avg() on BigDecimal column hits SqlFunctions.divide(BigDeciaml, BigDecimal),
> which further calls BigDecimal.divide(BigDecimal). This method will throw
> exception when the result has infinite digits after the decimal point, e.g.
> 10/9=1.11111...
> Alternatively, divide(BigDecimal divisor, MathContext mc) should be called
> instead, so BigDecimal knows the precision and rounding mode to handle the
> infinite number.
