$F\left(a,b;c;x\right)$ denotes the hypergeometric function $F$ (also known as the generalized hypergeometric function ${}_{2}F_{1}\left(a,b;c;x\right)$); see DLMF (15.2.1). This function is not defined when $c$ is a non-positive integer. Computations are for real $a,b,c$ and $x$, which currently must satisfy all of the conditions:

$\left|x\right|<1$,

either $a$ or $b$ must be integer,

if $a,b$ are non-negative integers and $c$ is an integer, then $c>\mathrm{min}(a,b)$,

if $a,c$ are integers but $b$ is not, then $c>a$,

if $b,c$ are integers but $a$ is not, then $c>b$.
