◆ unit_cast()

template<typename T , typename Units , class = std::enable_if_t<std::is_arithmetic<T>::value && traits::is_unit_t<Units>::value>>

constexpr T units::unit_cast ( const Units & value )

inlineconstexprnoexcept

Casts a unit container to an arithmetic type.

unit_cast can be used to remove the strong typing from a unit class, and convert it to a built-in arithmetic type. This may be useful for compatibility with libraries and legacy code that don't support unit_t types. E.g

meter_t unitVal(5);

double value = units::unit_cast<double>(unitVal); // value = 5.0

Template Parameters

T	Type to cast the unit type to. Must be a built-in arithmetic type.

Parameters

value Unit value to cast.
