----------------------------------------
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.
