*Not to be confused with Definition:Convergent of Continued Fraction.*

## Definition

Let $\struct {F, \norm {\,\cdot\,}}$ be a valued field.

Let $C = (a_n)_{n\geq 0}$ be a infinite continued fraction in $F$.

Then $C$ **converges** to its **value** $x \in F$ if and only if the following hold:

- For all natural numbers $n \in \N_{\geq 0}$, the $n$th denominator is nonzero
- The sequence of convergents $\sequence{C_n}_{n\geq 0}$ converges to $x$.

## Also known as

The **value** of an infinite continued fraction is also known as its **limit**.
