From cppreference.com
Defined in header <bit>


template< class T > constexpr T ceil2(T x) noexcept; 
(since C++20)  
Calculates the smallest integral power of two that is not smaller than x
. If that value is not representable in T
, the result is unspecified.
This overload only participates in overload resolution if T
is an unsigned integer type (that is, unsigned char, unsigned short, unsigned int, unsigned long, unsigned long long, or an extended unsigned integer type).
[edit] Return value
The smallest integral power of two that is not smaller than x
, or an unspecified value if the result cannot be represented in T
.
