Tests: Fix test-math expected values
Some of the expected values in test-math were wrong, which caused some
tests to fail.
The updated values were generated by Python's math library, and rounded
to 6 decimals places:
>>> import math
>>> round(math.exp(20.99), 6)
1305693298.670892
Examples of failure outputs:
FAIL: ../Userland/Tests/LibM/test-math.cpp:98:
EXPECT_APPROXIMATE(exp(v.x), v.exp) failed with
lhs=1305693298.670892, rhs=1304956710.432034, (lhs-rhs)=736588.238857
FAIL: ../Userland/Tests/LibM/test-math.cpp:99:
EXPECT_APPROXIMATE(sinh(v.x), v.sinh) failed with
lhs=652846649.335446, rhs=652478355.216017, (lhs-rhs)=368294.119428
FAIL: ../Userland/Tests/LibM/test-math.cpp:100:
EXPECT_APPROXIMATE(cosh(v.x), v.cosh) failed with
lhs=652846649.335446, rhs=652478355.216017, (lhs-rhs)=368294.119429
