El valor devuelto es la parte entera del valor decimal; los dígitos fraccionarios se truncan.The return value is the integral part of the decimal value; fractional digits are truncated.

También puede convertir un Decimal valor en un entero de 64 bits mediante el operador de Explicit asignación.You can also convert a Decimal value to a 64-bit integer by using the Explicit assignment operator. Dado que el operador realiza una conversión de restricción, debe utilizar un operador de conversión C# en o una función de conversión en Visual Basic.Because the operator performs a narrowing conversion, you must use a casting operator in C# or a conversion function in Visual Basic.
