The previous value had twelve signficant digits which is quite below the maximum precision of double floating numbers. In this change the value returned by Python for the expression math.pi * 2 is used. This value is the same returned by std::cos(-1) * 2 with 16 significant digits.

I didn't try running the tests because the set up doesn't look straight forward and the tolerances used for comparison in test_trig.cpp are rather large. I didn't find any mention of degree or gradian elsewhere in the tests. |
