Neal Richardson resolved ARROW-7860. ------------------------------------ Resolution: Duplicate > [C++] Support cast to/from halffloat > ------------------------------------ > > Key: ARROW-7860 > URL: https://issues.apache.org/jira/browse/ARROW-7860 > Project: Apache Arrow > Issue Type: Improvement > Components: C++, C++ - Compute > Reporter: Neal Richardson > Priority: Major > Fix For: 1.0.0 > > > In trying to do ARROW-7753 I realized I couldn't make a halffloat. I tried > creating a float64 (as R does naturally) and casting to float16, but it's not > implemented. Looking at compute/kernels/cast.cc, and the associated source in > compute/kernels/generated/codegen.py, {{FLOATING_TYPES = ['Float', > 'Double']}}. Maybe halffloat just needs to be added there? > Aside: searching through the code, it seems that this limitation of float > types to float32 and float64 is the norm. -- This message was sent by Atlassian Jira (v8.3.4#803005)
