/**
 * Annex G.6.4.2 The csqrt functions
 * csqrt(conj(z)) = conj(csqrt(z)).
 * csqrt(+/-0 + i0) returns +0 + i0.
 * csqrt(x + i inf) returns +inf + i inf, for all x (including NaN).
 * csqrt(x + iNaN) returns NaN + iNaN and optionally raises the invalid floating-point exception, for finite x.
 * csqrt(-inf + iy) returns +0 + i inf, for finite positive-signed y.
 * csqrt(+inf + iy) returns +inf + i0, for finite positive-signed y.
 * csqrt(-inf + iNaN) returns NaN +/- i inf (where the sign of the imaginary part of the result is unspecified).
 * csqrt(+inf + iNaN) returns +inf + iNaN.
 * csqrt(NaN + iy) returns NaN + iNaN and optionally raises the invalid floating-point exception, for finite y.
 * csqrt(NaN + iNaN) returns NaN + iNaN.
