Datos de punto fijo

Aproximaciones eficientes para valores de punto no flotante

Los números de punto fijo utilizan un esquema de cifrado basado en enteros para aproximar números reales. Ofrecen una alternativa eficiente al cálculo numérico que no requiere compatibilidad con el punto flotante en el hardware del sistema subyacente. Minimice la pérdida de precisión en cálculos ajustando el esquema de cifrado.
