ZetaZero
Details

- Mathematical function, suitable for both symbolic and numerical manipulation.
- For positive k, ZetaZero[k] represents the zero of
on the critical line
that has the k
smallest positive imaginary part.
- For negative k, ZetaZero[k] represents zeros with progressively larger negative imaginary parts.
- N[ZetaZero[k]] gives a numerical approximation to the specified zero.
- ZetaZero can be evaluated to arbitrary numerical precision.
- ZetaZero automatically threads over lists.
