Pindikura Ravindra created ARROW-3701:

             Summary: [Gandiva] Add support for decimal operations
                 Key: ARROW-3701
                 URL: https://issues.apache.org/jira/browse/ARROW-3701
             Project: Apache Arrow
          Issue Type: Task
          Components: Gandiva
            Reporter: Pindikura Ravindra
            Assignee: Pindikura Ravindra

To begin with, will add support for 128-bit decimals. There are two parts :
 # llvm_generator needs to understand decimal types (value, precision, scale)
 # code decimal operations : add/subtract/multiply/divide/mod/..
 ** This will be c++ code that can be pre-compiled to emit IR code
