Definition:Value of Continued Fraction/Infinite

Definition
Let $F$ be a field with absolute value $|\cdot|$.

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

Then $C$ converges to its value $x \in F$ the following hold:
 * 1) For all natural numbers $n \in \N_{\geq 0}$, the $n$th denominator is nonzero
 * 2) The sequence of convergents $(C_n)_{n\geq 0}$ converges to $x$.

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