half_nonnegative()

template<typename N >

auto algo::half_nonnegative ( N  n ) -> typename std::enable_if_t<std::is_integral<N>::value, N>

noexcept

Compute half of a non-negative integral number.

This function computes half of a non-negative integral number. For integral types, it uses unsigned arithmetic to avoid overflow when dealing with negative numbers.

\[ \lfloor n/2 \rfloor \]

Template Parameters

N	The integral type

Parameters

[in]

n

The non-negative number to halve

Returns

Half of the input number

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

\[ \lfloor n/2 \rfloor \]
