`mp_units::utility::abs`¶

Absolute value of an uncertain value

Synopsis¶

[[nodiscard]] constexpr uncertain abs(uncertain const& arg)
  requires requires { abs(arg.value()); } || requires { std::abs(arg.value()); };

Note

This function is a hidden friend of uncertain, declared only inside that class: it can be found only through argument-dependent lookup.

Uncertainty is preserved unchanged.
