## Definition

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

Let $C = \sequence {a_n}_{n \mathop \ge 0}$ 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 $n \in \N_{\ge 0}$, the $n$th denominator is nonzero
- The sequence of convergents $\sequence {C_n}_{n \mathop \ge 0}$ converges to $x$.

## Also known as

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