Minor update.  The rhs should have csqrt instead of sqrt.

 For numbers with negative imaginary parts, the above special cases
 apply given the identity:
-.Dl csqrt(conj(z) = conj(sqrt(z))
+.Dl csqrt(conj(z)) = conj(csqrt(z))
 Note that the sign of \*(Na is indeterminate.
 Also, if the real or imaginary part of the input is finite and
 an \*(Na is generated, an invalid exception will be thrown.
