`tan` tangent function missing roots

1

I expected roots to find all the roots of the tangent function in the simple case below, but it doesn't. The roots should be $n \pi$ with $n$ an integer....

Implementing the Riemann-Siegel Formula to find zeros of the Riemann Zeta Function with Roots.jl

3

I am interested in implementing a version of the [Riemann-Siegel formula](https://en.wikipedia.org/wiki/Riemann%E2%80%93Siegel_formula) for calculating [non-trivial zeros of the Riemann zeta function](https://en.wikipedia.org/wiki/Riemann_zeta_function#Zeros,_the_critical_line,_and_the_Riemann_hypothesis) in Julia. I can "successfully" get "manually finding roots by...
