Sergey B Kirpichev	e6fad7a0e3	gh-122637: fix tanh(±0+infj) and tanh(±0+nanj) to return ±0+nanj (#122638 ) As per C11 DR#471, ctanh (0 + i NaN) and ctanh (0 + i Inf) should return 0 + i NaN (with "invalid" exception in the second case). This has corresponding implications for ctan(z), as its errors and special cases are handled as if the operation is implemented by -ictanh(iz). This patch fixes cmath's code to do same.

gh-122637: fix tanh(±0+infj) and tanh(±0+nanj) to return ±0+nanj (#122638 )

As per C11 DR#471, ctanh (0 + i NaN) and ctanh (0 + i Inf) should return
0 + i NaN (with "invalid" exception in the second case).  This has
corresponding implications for ctan(z), as its errors and special cases
are handled as if the operation is implemented by -i*ctanh(i*z).
This patch fixes cmath's code to do same.

gh-121889: cmath.acosh(0+nanj) returns nan+pi/2j (#121892 )

As per C11 DR#471 (adjusted resolution accepted for C17), cacosh (0 +
iNaN) should return NaN ± i pi/2, not NaN + iNaN.  This patch
fixes cmath's code to do same.
