A '''root-finding algorithm''' is a numerical method, or [[algorithm]], for finding a value '''x''' such that '''f(x) = 0''', for a given [[Function (mathematics)|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.
