Dear maintainer,
The bart-cuda autopkgtest fails when run against glibc 2.41, which is
currently in experiemntal. It fails with [1]:

| 3774s make: *** [tests/traj.mk:53: tests/test-traj-rot] Error 1
Investigation shows that this is due to improved accuracy of the atan2f
function in glibc 2.41. 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.
Regards
Aurelien
