Call Compiled Code from Compiled Code

The Wolfram Compiler works well with compiled Wolfram Language code. A compiled function can accept other compiled functions as arguments. The abstractive power that this provides allows a tremendous amount of innovative solutions to be written.

The function bisectionRoot[f, lim₀, lim₁] finds a root of f by bisecting the interval from lim₀ to lim₁. The rule of the form {in₁, in₂, …}->out in the second argument of Typed indicates that the variable f is a function, in this case one that takes and returns a "Real64".

Compile the function whose root will be found.

Find several roots of f. Of course, a different function could have been studied without changing bisectionRoot.
