`mp_units::epsilon`¶

Returns the epsilon of the quantity

Synopsis¶

Declared in <mp-units/math.h>

template<typename Rep, Reference R>
  requires RepresentationOf<Rep, get_quantity_spec(R{})> && requires { std::numeric_limits<Rep>::epsilon(); }
[[deprecated("2.5.0: Use `std::numeric_limits<Quantity>::epsilon()` instead"), nodiscard]] constexpr quantity<R{}, Rep>
  epsilon(R r) noexcept;

Warning

Deprecated: 2.5.0: Use `std::numeric_limits<Quantity>::epsilon()` instead. Use of this entity is allowed but discouraged.

Description¶

The returned value is defined by a std::numeric_limits<typename Q::rep>::epsilon().

Return Value¶

Quantity The epsilon value for quantity's representation type

Note

The return value should not be discarded.
