make_signed Class

Makes type or the smallest signed type greater than or equal in size to type.

Syntax

template <class T>
struct make_signed;

template <class T>
using make_signed_t = typename make_signed<T>::type;

Parameters

T
The type to modify.

Remarks

An instance of the type modifier holds a modified-type that is T if is_signed<T> holds true. Otherwise it is the smallest unsigned type UT for which sizeof (T) <= sizeof (UT).
