 \subsection{Data types}
-Data types supported by VCF are: Integer (32-bit, signed), Float (32-bit IEEE-754, formatted to match one of the regular expressions \verb|^[-+]?[0-9]*\.?[0-9]+([eE][-+]?[0-9]+)?$| or \verb"^[-+]?(INF|INFINITY|NAN)$" case insensitively), Flag, Character, and String.
-For the Integer type, the values from $-2^{31}$ to $-2^{31}+7$ cannot be stored in the binary version and therefore are disallowed in both VCF and BCF, see \ref{BcfTypeEncoding}.
