## Detailed Description

### template<typename VT = signed char>
class mysqlpp::tiny_int< VT >

Class for holding an SQL `TINYINT` value.

This is required because the closest C++ type, `char`, doesn't have all the right semantics. For one, inserting a `char` into a stream won't give you a number. For another, if you don't specify signedness explicitly, C++ doesn't give a default, so it's signed on some platforms, unsigned on others.

The template parameter is intended to allow instantiating it as tiny_int<unsigned char> to hold `TINYINT` `UNSIGNED` values. There's nothing stopping you from using any other integer type if you want to be perverse, but please don't do that.

Several of the functions below accept an `int` argument, but internally we store the data as a `char` by default. Beware of integer overflows!
