[GitHub] [beam] lukecwik opened a new pull request #15329: [BEAM-12755] Stop throwing exceptions during formatting and calculation of a percentile
lukecwik opened a new pull request #15329:
URL: https://github.com/apache/beam/pull/15329
String.format already uses HALF_UP rounding mode.
Also using NaN for an invalid value instead of throwing an exception which is difficult to expect users to work with.

Maybe this code shouldn't ever be called if totalNumOfRecords == 0
This feature is only used to print some info logging.
So ti could just print something else in this case
WDYT @ihji ?

Review comment:
Just curious. Did you decide to make this change because you saw this exception thrown in a user pipeline? (Its possible the code is designed to not invoke this method in this case). Just wondering if actual pipelines are hitting this?
Or did you just decide to make this change to make to remove the exception, make the code safer, etc.
