Oct 1, 2025Monthly summary for 2025-10 focusing on numerical safety and reliability in the apytypes/apytypes repository. The primary deliverable was a bug fix to overflow handling in APyFloat.from_float (cast_from_double), ensuring large values overflow to infinity instead of producing incorrect finite results. This change strengthens numerical correctness and consistency with IEEE-754 expectations, reducing risk of downstream miscalculations and improving API reliability.
