Functions
template<std::floating_point T>
constexpr T	nem::is_infinite (T value) noexcept
template<std::floating_point T>
constexpr T	nem::is_nan (T value) noexcept
template<std::floating_point T>
constexpr T	nem::copysign (T to, T from) noexcept
	Copies the sign of {from} over to {to}. If the signs were the same, it doesn't change.
template<nem::scalar_type T>
constexpr T	nem::sign (T value) noexcept
template<typename T >
constexpr T	nem::abs (T value) noexcept
template<nem::scalar_type T>
constexpr bool	nem::is_zero (T a) noexcept
	Is a nearly 0? Given an Epsilon > 0, within each all numbers are considered indistinguisable from 0, |a| < eps.
template<nem::scalar_type T>
constexpr bool	nem::is_zero_or_neg (T a) noexcept
template<nem::scalar_type T>
constexpr bool	nem::equal (T a, T b) noexcept
	Are a and b nearly equal? Given an Epsilon > 0, within each all numbers are considered indistinguisable from 0, |a - b| < eps.
template<nem::scalar_type T>
constexpr T	nem::get_max (T a, T b) noexcept
template<nem::scalar_type T>
constexpr T	nem::get_min (T a, T b) noexcept

template<typename T >
constexpr T	nem::pow4 (T value) noexcept
template<typename T >
constexpr T	nem::sqr (T value) noexcept

constexpr T	nem::cube (T value) noexcept
template<nem::scalar_type T>
constexpr T	nem::truncate (T value) noexcept
template<nem::scalar_type T>
constexpr T	nem::floor (T value) noexcept
	Floors always towards -infinity.
template<nem::scalar_type T>
constexpr T	nem::ceil (T value) noexcept
	Ceils always towards +infinity.
template<nem::scalar_type T>
constexpr T	nem::mod (T a, T b)
	Calculates euclidean modulo of a % b = r, where r belongs to [0, b). Unline standard C++ modulo operator, works with any floating-point numbers and can never yield negative numbers.
template<std::floating_point T>
constexpr T	nem::frac (T value) noexcept
	Returns the fractional part of the floating-point number, with respect to sign 3.5 -> 0.5 4.0 -> 0.0 -2.1 -> -0.1.
template<std::floating_point T>
constexpr T	nem::round (T value) noexcept
template<std::floating_point T>
constexpr T	nem::floor (T value, T step)
template<std::floating_point T>
constexpr T	nem::ceil (T value, T step)
template<std::floating_point T>
constexpr T	nem::round (T value, T step)
template<nem::scalar_type T>
constexpr T	nem::repeat (T value, T lengthExcl)
	Unwinds number to 0 when goes past length. Lengh is excluded: when value == lengthExcl, value becomes 0.
template<nem::scalar_type T>
constexpr T	nem::repeat (T value, T minIncl, T maxExcl)
	Unwinds number to minimum when goes past maximum. Max value is excluded: when value == maxExcl, value becomes minIncl.
template<nem::scalar_type T>
constexpr T	nem::pingpong (T value, T length)
template<nem::scalar_type T>

template<nem::scalar_type T>
constexpr T	nem::remap (T value, T fromMin, T fromMax, T toMin, T toMax)
template<std::floating_point T>
constexpr T	nem::is_whole (T value)
	Is a floating point number whole (same as integer)
