- The method `set_bits` was missing, causing compilation failures when
  using bits_to_fixed method.
- The copyright of the concerned file has been updated.

# HLS Arbitrary Precision Types Library
This repo provides simulation code of HLS Arbitrary Precision Types.
This repository provides simulation code of HLS Arbitrary Precision Types.
The code is based from headers shipped with Vivado,
The code is based from headers shipped with Vivado (*in 2019...*),
but due to absence of synthesis support **it should not be used in an HLS project targeting FPGA**.
For synthesis, the repository owner (A.K.A [DrasLorus](https://github.com/DrasLorus)) strongly recommends the use of Xilinx® provided headers, which are *unfortunately* proprietary software.
## Compatibility
Tested with g++ (GCC) 6.2.0 on x86_64 GNU/Linux.
- *(Legacy)* Tested with g++ (GCC) 6.2.0 on x86_64 GNU/Linux.
- Tested with clang (LLVM) 13.0.0 and g++ (GCC) 11.1.0 on x86_64 GNU/Linux.
