In details bart-cuda computes atan2f(0x1.166202p-4, 0x1.e22c5ap-4) and it expects it to be 30.00000 when converted from radian to degrees, ie it expects the atan2f function to return 0x1.0c1524p-1. With glibc 2.41, the atan2f function has been improved [2] and now returns instead 0x1.0c1522p-1 which is closer to the real value than 0x1.0c1524p-1. This corresponds to 29.999998 when converted to degrees. The patch below fixes the issue by accepting both values.
