A root-finding algorithm is a numerical method, or algorithm, for finding a value x such that f(x) = 0, for a given function f. Such an x is called a root of the function f.
This article is concerned with finding scalar, real or complex roots, approximated as floating point numbers.
Integer roots
Finding integer roots or exact algebraic roots are separate problems, whose algorithms have little in common with those discussed here. See Diophantine equation for integer roots.
