Number Precision
number-precision es una librería matemática de JavaScript y utilidad de aritmética de precisión arbitraria. Proporciona un conjunto de funciones para realizar sumas, restas, multiplicaciones y divisiones evitando los errores de redondeo comunes en las operaciones estándar de punto flotante binario.
El proyecto se centra en mantener una precisión decimal controlada para asegurar resultados matemáticos consistentes. Esto lo hace aplicable para cálculos financieros donde se requieren valores de moneda exactos, así como para el procesamiento de datos de alta precisión en informes científicos o técnicos.
Sus capacidades incluyen aritmética de punto flotante precisa y normalización de datos numéricos mediante el redondeo de valores a precisiones decimales específicas.
