Solve f(z)=0 over ℂ. Use variable z. Examples: z^2+4, exp(z)-z, z^32-2^z.

f(z) — function (Math.js syntax) f'(z) — derivative (optional; improves convergence)

Real range [xmin,xmax]

Imag range [ymin,ymax]

Grid (per axis)

Max iterations

Tolerance (|f(z)|)

Root merge radius

Single initial guess

Tips: Provide f'(z) when you can. Increase grid to find more roots; expand ranges for large-magnitude solutions. For z^32-2^z, include 256 on the real axis to catch the exact root.
