[jira] [Created] (ARROW-6436) [C++] vendor a half precision floating point library

Benjamin Kietzman created ARROW-6436:
----------------------------------------

             Summary: [C++] vendor a half precision floating point library
                 Key: ARROW-6436
                 URL: https://issues.apache.org/jira/browse/ARROW-6436
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C++
            Reporter: Benjamin Kietzman


Clang and GCC provide _Float16 and there are numerous polyfills which can emulate a 16 bit float for other platforms. This would fill a hole in the kernels and other code which don't currently support HALF_FLOAT.
