Benedict updated CASSANDRA-15232: --------------------------------- Fix Version/s: 4.0 > Arithmetic operators over decimal truncate results > -------------------------------------------------- > > Key: CASSANDRA-15232 > URL: https://issues.apache.org/jira/browse/CASSANDRA-15232 > Project: Cassandra > Issue Type: Improvement > Components: CQL/Semantics > Reporter: Benedict > Priority: Normal > Fix For: 4.0 > > > The decimal operators hard-code a 128 bit precision for their computations. > Probably a precision needs to be configured or decided somehow, but it’s not > clear why 128bit was chosen. Particularly for multiplication and addition, > it’s very unclear why we truncate, which is different to our behaviour for > e.g. sum() aggregates. Probably for division we should also ensure that we > do not reduce the precision of the two operands. A minimum of decimal128 > seems reasonable, but a maximum does not. -- This message was sent by Atlassian JIRA (v7.6.14#76016) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
