/**
 * Annex G.6.2.4 The ccosh functions
 * ccosh(conj(z)) = conj(ccosh(z)) and ccosh is even.
 * ccosh(+0 + i0) returns 1 + i0.
 * ccosh(+0 + i inf) returns NaN +/- i0 (where the sign of the imaginary part of the result is unspecified) and raises the invalid floating-point exception.
 * ccosh(+0 + iNaN) returns NaN +/- i0 (where the sign of the imaginary part of the result is unspecified).
 * ccosh(x + i inf) returns NaN + iNaN and raises the invalid floating-point exception, for finite nonzero x.
 * ccosh(x + iNaN) returns NaN + iNaN and optionally raises the invalid floating-point exception, for finite nonzero x.
 * ccosh(+inf + i0) returns +inf + i0.
 * ccosh(+inf + iy) returns +inf cis(y), for finite nonzero y.
 * ccosh(+inf + i inf) returns +/-inf + iNaN (where the sign of the real part of the result is unspecified) and raises the invalid floating-point exception.
 * ccosh(+inf + iNaN) returns +inf + iNaN.
 * ccosh(NaN + i0) returns NaN +/- i0 (where the sign of the imaginary part of the result is unspecified).
 * ccosh(NaN + iy) returns NaN + iNaN and optionally raises the invalid floating-point exception, for all nonzero numbers y.
 * ccosh(NaN + iNaN) returns NaN + iNaN.
