Numerical approximation laboratory
Three algorithms, three ways to approach a number. Change the inputs, advance one step at a time or start playback.
Bisection: keep the half-interval that contains √a. The root of f(t)=t²−a stays enclosed.

How the error changes
Each bar shows the absolute error at one step. The scale is relative to the first displayed error.
The browser calculates the reference using √a or eˣ; it is a highly accurate numerical estimate, not a proof.
