std::overflow_error
| Defined in header

| class overflow_error;

||
Defines a type of object to be thrown as exception. It can be used to report arithmetic overflow errors (that is, situations where a result of a computation is too large for the destination type)
The only standard library components that throw this exception are std::bitset::to_ulong and std::bitset::to_ullong.
The mathematical functions of the standard library components do not throw this exception (mathematical functions report overflow errors as specified in math_errhandling). Third-party libraries, however, use this. For example, boost.math throws std::overflow_error if boost::math::policies::throw_on_error is enabled (the default setting).
