FAQ ===== Precision Issues Caused by ffast-math Flag ------------------------------------------ Precision issues in computations may be caused by the ``ffast-math`` compiler flag which is enabled by default in some tasks. This flag allows the compiler to violate strict IEEE 754 compliance for floating-point operations, potentially resulting in faster execution but less accurate results. If you encounter precision-related issues, users can remove this flag from their task configuration files. For kernel developers, you can manually specify compilation flags using UnsafeMacros to control the behavior of specific kernels.
