Detailed Description

template<typename Unpacked_t>
class tlfloat::TLFloat< Unpacked_t >

This is a trivially copyable generic template class that represents an IEEE 754 floating-point number. By adjusting the template parameters, it can represent an IEEE 754 floating-point number of any precision. The data size and data structure of the object are the same as the corresponding floating-point number represented in the IEEE 754 format.
