The old macos-11 image is now removed. Update to running release macos-latest.

• picsar_tables test: some numerical values vary on near-machine precision but compare without an epsilon

[ax3l]

@lucafedeli88 the table test seems to need a tolerance review on the last significant digits. Can you help with this? 🙏

[lucafedeli88]

Hi @ax3l ,
thanks for this PR!
Precision for the failing test (test_picsar_tables.cpp) is set by these two variables

//Tolerance for double precision calculations
const double double_tolerance = 1.0e-12;

//Tolerance for single precision calculations
const float float_tolerance = 1.0e-5;

We may try to increase the tolerance by a small factor (e.g., 2 or 5) and see if the tests pass.
I can do that if you want!
Besides of that, the PR looks good to me: as soon as the tests pass we can merge it.

Hi @lucafedeli88,

Thanks a lot - I pushed a few updates, but happy if you can take it over for the tolerances :)

[ax3l]

Ah, the tolerances are not used in the tests that actually fail:

• BOOST_CHECK_EQUAL for the linear_function

[lucafedeli88]

Oh, sorry! I didn't know that the failing test actually used BOOST_CHECK_EQUAL.
I think that your change makes sense here.
Thanks for this PR!
