Resultado de redondear d al número entero más próximo, hacia cero.The result of d rounded toward zero, to the nearest whole number.

Ejemplos

En el ejemplo de código siguiente Truncate se usa el método para descartar los Decimal dígitos fraccionarios de varios valores.The following code example uses the Truncate method to discard the fractional digits of several Decimal values.

// Example of the Decimal::Negate, Decimal::Floor, and 
// Decimal::Truncate methods. 
using namespace System;

// Display Decimal parameters and the method results.
void ShowDecimalFloorNegTrunc( Decimal Argument )
{
   String^ dataFmt = "{0,-30}{1,26}";
   Console::WriteLine();
   Console::WriteLine( dataFmt, "Decimal Argument", Argument );
   Console::WriteLine( dataFmt, "Decimal::Negate( Argument )", Decimal::Negate( Argument ) );
   Console::WriteLine( dataFmt, "Decimal::Floor( Argument )", Decimal::Floor( Argument ) );
   Console::WriteLine( dataFmt, "Decimal::Truncate( Argument )", Decimal::Truncate( Argument ) );
}

int main()
{
   Console::WriteLine( "This example of the \n"
   "  Decimal::Negate( Decimal ), \n"
   "  Decimal::Floor( Decimal ), and \n"
   "  Decimal::Truncate( Decimal ) \n"
   "methods generates the following output." );
   
   // Create pairs of Decimal objects.
   ShowDecimalFloorNegTrunc( Decimal::Parse( "0" ) );
   ShowDecimalFloorNegTrunc( Decimal::Parse( "123.456" ) );
   ShowDecimalFloorNegTrunc( Decimal::Parse( "-123.456" ) );
   ShowDecimalFloorNegTrunc( Decimal(1230000000,0,0,true,7) );
   ShowDecimalFloorNegTrunc( Decimal::Parse( "-9999999999.9999999999" ) );

Este método se d redondea hacia cero, al número entero más próximo, que corresponde a descartar los dígitos situados después del separador decimal.This method rounds d toward zero, to the nearest whole number, which corresponds to discarding any digits after the decimal point.
