=== Assistant: 這裡是不同精度 2π2\pi2π 下的模運算結果: === 這裡是不同精度 2π2\pi2π 下的模運算結果: | | | | | --- | --- | --- | | | | | | | | | | | | | | | | | | | | | | | | | ✅ 可以看出 模運算結果對精度非常敏感,尤其是 5201314 mod 2π2\pi2π 的值在不同精度下差異極大,這會直接影響三角函數的象限和大小比較。 如果要比較 cos114514\cos114514cos114514 和 cos5201314\cos5201314cos5201314 的大小,必須用最精確的 2π ≈ 6.2831853,才能得到正確結果。
