Десятичное число для усечения.The decimal number to truncate.

Возвраты

Результат округления d в сторону нуля до ближайшего целого числа.The result of d rounded toward zero, to the nearest whole number.

Примеры

В следующем примере кода используется Truncate метод отказаться от цифр дробной части из нескольких Decimal значения.The following code example uses the Truncate method to discard the fractional digits of several Decimal values.

Комментарии

Этот метод округляет d сторону нуля до ближайшего целого числа, который соответствует удалению всех цифр после десятичной запятой.This method rounds d toward zero, to the nearest whole number, which corresponds to discarding any digits after the decimal point.
