## MP-UNITS & STANDARDIZATION ## mp-units: C++20/23 quantities and units library ## • Compile-time safety – correct handling of physical quantities, units, and numerical values ## mp-units: C++20/23 faster than working with fundamental types – no runtime overhead – no space size overhead ## mp-units: C++20/23 quantities and units library ## • Compile-time safety – correct handling of physical optimized for readable compilation errors and great debugging experience – easy to use and flexible ## mp-units: C++20/23 quantities and units library ## • Compile-time safety – correct handling of physical
