◆ copysign()

template<class UnitTypeLhs , class = std::enable_if_t<traits::is_unit_t<UnitTypeLhs>::value>>

UnitTypeLhs units::math::copysign	(	const UnitTypeLhs	x,
		const UNIT_LIB_DEFAULT_TYPE	y )

constexprnoexcept

Overload to copy the sign from a raw double.

◆ cpow()

template<int power, class UnitType , class = typename std::enable_if<traits::has_linear_scale<UnitType>::value, int>>

auto units::math::cpow ( const UnitType & value ) -> unit_t<typename units::detail::power_of_unit<power, typename units::traits::unit_t_traits<UnitType>::unit_type>::type, typename units::traits::unit_t_traits<UnitType>::underlying_type, linear_scale>

constexprnoexcept

computes the value of value raised to the power as a constexpr

Only implemented for linear_scale units. Power must be known at compile time, so the resulting unit type can be deduced. Additionally, the power must be a positive, integral, value.

Template Parameters

power exponential power to raise value by.

Parameters

[in] value unit_t derived type to raise to the given power

Returns:: new unit_t, raised to the given exponent

◆ max()

template<class UnitTypeLhs , class UnitTypeRhs >

UnitTypeLhs units::math::max	(	const UnitTypeLhs &	lhs,
		const UnitTypeRhs &	rhs )

constexpr

◆ pow()

template<int power, class UnitType , class = typename std::enable_if<traits::has_linear_scale<UnitType>::value, int>>

constexprnoexcept
