Functions
template<typename T >
constexpr bool	is_power_of_2 (const T value)
	Determines whether value is a power-of-2 number.
template<std::size_t BASE, typename T >
constexpr bool	is_power_of (const T value)
	Determines whether value is a power-of-BASE number. Checks the equality BASE^n == value, where n is an integer.
template<std::integral T>
T	ceil_div (const T numerator, const T denominator)
	Divide numerator by denominator and round up to integer. Both inputs must be positive integer. Specifically, numerator >= 0 and denominator > 0.
template<std::integral T>
T	next_multiple (const T value, const T multiple)
	Get the next number that is an integer multiple of multiple. Specifically, get the minimum number x = C * multiple >= value where C is an integer >= 0. Currently supports positive integers only.
template<std::integral T>
T	next_power_of_2_multiple (const T value, const T multiple)
	Same as next_multiple(T, T) except that multiple must be a power of 2 number.

ceil_div()

template<std::integral T>

T ph::math::ceil_div ( const T numerator, const T denominator )

inline

Divide numerator by denominator and round up to integer. Both inputs must be positive integer. Specifically, numerator >= 0 and denominator > 0.

is_power_of()

template<std::size_t BASE, typename T >

bool ph::math::is_power_of ( const T value )

inlineconstexpr

Determines whether value is a power-of-BASE number. Checks the equality BASE^n == value, where n is an integer.

is_power_of_2()

template<typename T >

bool ph::math::is_power_of_2 ( const T value )

inlineconstexpr

Determines whether value is a power-of-2 number.

next_multiple()

template<std::integral T>

T ph::math::next_multiple ( const T value, const T multiple )

inline

Get the next number that is an integer multiple of multiple. Specifically, get the minimum number x = C * multiple >= value where C is an integer >= 0. Currently supports positive integers only.

next_power_of_2_multiple()

template<std::integral T>

T ph::math::next_power_of_2_multiple ( const T value, const T multiple )

inline

Same as next_multiple(T, T) except that multiple must be a power of 2 number.
