URL: https://github.com/apache/druid/pull/10014
### Description
Double.NaN, Double.POSITIVE_INFINITY and Double.NEGATIVE_INFINITY are not
real
numbers. Because of this, they can not be converted to BigDecimal and instead
throw a NumberFormatException.
This change adds support for calculations that produce these numbers either
for use in the `ROUND` function or the HavingSpecMetricComparator by not
attempting to convert the number to a BigDecimal.
The bug in `ROUND` was first introduced in #7224 where we added the ability
to
round to any decimal place. This PR changes the behavior back to using
`Math.round` if we recognize a number that can not be converted to a
BigDecimal.
