[jira] [Created] (SPARK-59111) Java native IEEE 754 Decfloat port from Intel

Serge Rielau created SPARK-59111:
------------------------------------

             Summary: Java native IEEE 754 Decfloat port from Intel 
                 Key: SPARK-59111
                 URL: https://issues.apache.org/jira/browse/SPARK-59111
             Project: Spark
          Issue Type: New Feature
          Components: Spark Core
    Affects Versions: 5.0.0
            Reporter: Serge Rielau


To support DECFLOAT with a full roster of arithmetic and special values we want a IEEE 754 compliant math library. BigDecimal is not suifficient (not IEEE754) and teh existing Intel library is in C and requires JNI call.
In thsi Jira we port the Intel library to Java.
