pulg. Calcula el resto de la operación de punto flotante x/y división como la función
4) remainder hace. Además, la señal y al menos tres de los últimos bits de x/y se almacenarán en quo .Original:
Computes the remainder of the floating point division operation x/y as the
remainder function does. Additionally, the sign and at least the three of the last bits of x/y will be stored in quo.The text has been machine-translated via Google Translate.

Si algún argumento es de tipo integral, que se convierte en double. Si cualquier otro argumento es long double, entonces el tipo de retorno es long double, de lo contrario es double
Original:
If any argument has integral type, it is cast to double. If any other argument is long double, then the return type is long double, otherwise it is double

[editar] Notas
Esta función es útil cuando la aplicación de funciones periódicas con el período exactamente representable como un valor de coma flotante: en el cálculo de
sin(πx) para un x muy grande, llamando directamente std::sin puede resultar en un error grande, pero si el argumento de la función se reduce primero con std::remquo, los bits de orden bajo del cociente puede ser utilizado para determinar el signo y el resto puede ser usado para calcular el valor con alta precisión .Original:
This function is useful when implementing periodic functions with the period exactly representable as a floating-point value: when calculating
sin(πx) for a very large x, calling std::sin directly may result in a large error, but if the function argument is first reduced with std::remquo, the low-order bits of the quotient may be used to determine the sign and the remainder may be used to calculate the value with high precision.The text has been machine-translated via Google Translate.
