Will fixed-point math be supported?
Will fixed-point math be supported?
Hello GNU Tools
Looking into the GCC manual, chapter 6.15, it mentions fixed-point data types. However, when I include <stdfix.h> and try to use fixed-point types for eg. the RX111 target (GCC 4.8.4. 201801- – GNURX), I get the error “fixed-point types not supported for this target”.
Is fixed-point supported and I am doing something wrong or is it currently not supported?
If fixed-point is currently not supported, do you have any plans for future fixed-point support which I find very interesting to small targets with no FPU, like the RX111?
Best regards

Hello Frank,
Thank you for reaching out to us!
Unfortunately, fixed-point types are not supported by our GNURX toolchain. Also, for the near future, we do not have such a feature as part of our development roadmap. We apologize for the inconvenience.
Please let us know if there’s anything else that we can help with.
