In embedded systems without hardware FPUs, financial applications that demand exact decimal precision, and deterministic simulations that must produce identical results across platforms, <strong>fixed-point arithmetic</strong> provides a compelling alternative. Fixed-point numbers represent fractional values using integer types with an implicit scale factor — trading dynamic range for exact, deterministic computation.</p>
