Yibo Cai reassigned ARROW-13439: -------------------------------- Assignee: Yibo Cai > [C++] Unify BasicDecimal128 and BasicDecimal256 classes > ------------------------------------------------------- > > Key: ARROW-13439 > URL: https://issues.apache.org/jira/browse/ARROW-13439 > Project: Apache Arrow > Issue Type: Improvement > Components: C++ > Reporter: Yibo Cai > Assignee: Yibo Cai > Priority: Major > > BasicDecimal128 uses two dedicated int64 (higher, lower) to store the value. > It's possible to use std::array<uint64, 2> to store the value, just like > BasicDecimal256 does, and to unify the two classes. > As decimal operations are quite expensive, guess this indirection won't cause > performance loss. -- This message was sent by Atlassian Jira (v8.3.4#803005)
