14:20:17@telegram_5639215:t2bot.ioAntonio Álvarez (Telegram)No lo hace ya al trabajar con decimales? Pensaba que sí, pero ahora tengo dudas😂
14:21:53@telegram_2924680:t2bot.ioOscar Lozano (Telegram)Yo pensaba eso pero pierdo precisión en operaciones con muchos decimales
14:22:27@telegram_2924680:t2bot.ioOscar Lozano (Telegram)Si almaceno una variable con 10 decimales
14:22:58@telegram_2924680:t2bot.ioOscar Lozano (Telegram)Por más que le pida que me lo muestre luego con tantos decimales , los últimos me los pone a cero o cambiados
14:23:54@telegram_5639215:t2bot.ioAntonio Álvarez (Telegram)Quizás el tipo de dato Decimal o usar numpy.float128?

>>> import numpy as np
>>> np.array([1.0]).dtype
dtype('float64')
14:24:52@telegram_2397373:t2bot.ioJuan Luis Cano (Telegram)python ya trabaja por defecto con flotantes de 64 bit
14:25:18@telegram_2397373:t2bot.ioJuan Luis Cano (Telegram)si estás perdiendo decimales, ¿no será que estás haciendo alguna resta y estás sufriendo "catastrophic cancellation"?

Si almaceno una variable con 10 decimales
¿cómo estás controlando el número de decimales?

¿cómo estás controlando el número de decimales?
Perdona, no lo estoy haciendo , pq ya estoy haciendo pruebas por el terminal y por eso se lo datos que meto
14:30:55@telegram_2397373:t2bot.ioJuan Luis Cano (Telegram) 
>>> "%.12f" % 1.1231231231
'1.123123123100'
14:31:43@telegram_2924680:t2bot.ioOscar Lozano (Telegram)Si, al pedirle que me los muestre lo hago asi
14:48:21@telegram_59004152:t2bot.ioJavi Blasco (Telegram) quiero hacer lo siguiente en pandas, y reconozco que es una libreria que me puede... El objetivo es, de un DataFrame, copiar ciertas lineas, cambiarles el valor a dos columnas, anhadirlas a un nuevo dataframe. Al hacerlo tal cual sugiere el enunciado (un .loc seguido de la asignacion de las columnas que cambio y anhadir con un .append a la nueva tabla va a velocidad negativa... Ideas?
14:49:08@telegram_52246437:t2bot.ioJuan Ignacio Rodríguez De León (Telegram)La representación de números decimales no es exacta si se está usando IEEE754
14:49:20@telegram_52246437:t2bot.ioJuan Ignacio Rodríguez De León (Telegram)En python y en cualquier otro lenguaje
14:50:41@telegram_52246437:t2bot.ioJuan Ignacio Rodríguez De León (Telegram)Por ejemplo, 0.1 no tiene representación exacta
14:52:36@telegram_52246437:t2bot.ioJuan Ignacio Rodríguez De León (Telegram)Prueba a hacer '%.32f' % 0.1
