Detailed Description

Main header for the qtty C++ wrapper library.

This header provides a modern, type-safe C++ interface to the qtty-ffi library. It includes:

• Template-based Quantity class with compile-time unit checking
• Operator overloading for natural arithmetic syntax
• User-defined literals for convenient quantity creation
• Support for the full qtty-ffi linear unit catalog, including pressure, solid angle, temperature, radiometry, photometric SI units, frequency, chemistry, electrical, and density families
• Compound quotient units such as velocity through CompoundTag

Usage example:

using namespace qtty;
 
// Create quantities using constructors or literals
Meter distance(1000.0);
auto time = 20.0_s;
 
// Perform arithmetic operations
auto doubled = distance * 2.0;
 
// Convert units
Kilometer km = distance.to<Kilometer>();
 
// Derived quantities (velocity)
auto velocity = distance / time;
 
// New dimensions
Hectare field(2.5);
Newton force(9.8);
Joule energy(500.0);
