Este operador admite la conversión explícita de a Decimal .UInt64 La sintaxis de estas conversiones explícitas depende del lenguaje y los compiladores de lenguaje individuales pueden proporcionar diferentes implementaciones y devolver resultados diferentes. En el ejemplo se muestran los distintos valores devueltos cuando se convierte explícitamente un Decimal valor en un UInt64 valor mediante C# y Visual Basic. Para realizar una conversión independiente del lenguaje, puede llamar al Decimal.ToUInt64(Decimal) método o Convert.ToUInt64(Decimal) .

Este operador admite la conversión explícita de a Decimal .UInt16 La sintaxis de estas conversiones explícitas depende del lenguaje y los compiladores de lenguaje individuales pueden proporcionar diferentes implementaciones y devolver resultados diferentes. En el ejemplo se muestran los distintos valores devueltos cuando se convierte explícitamente un Decimal valor en un UInt16 valor mediante C# y Visual Basic. Para realizar una conversión independiente del lenguaje, puede llamar al Decimal.ToUInt16(Decimal) método o Convert.ToUInt16(Decimal) .

Comentarios
Esta operación puede producir una pérdida de precisión, ya que un número de punto flotante de precisión única tiene menos dígitos significativos que .Decimal
Este operador admite la conversión explícita de a Decimal .Single La sintaxis de estas conversiones explícitas depende del lenguaje y los compiladores de lenguaje individuales pueden proporcionar diferentes implementaciones y devolver resultados diferentes. En el ejemplo se muestran los distintos valores devueltos cuando se convierte explícitamente un Decimal valor en un Single valor mediante C# y Visual Basic. Para realizar una conversión independiente del lenguaje, puede llamar al Decimal.ToSingle(Decimal) método o Convert.ToSingle(Decimal) .

Comentarios
Esta operación puede producir una pérdida de precisión, ya que un número de punto flotante de doble precisión tiene menos dígitos significativos que un Decimal.
Este operador admite la conversión explícita de a Decimal .Double La sintaxis de estas conversiones explícitas depende del lenguaje y los compiladores de lenguaje individuales pueden proporcionar diferentes implementaciones y devolver resultados diferentes. En el ejemplo se muestran los distintos valores devueltos cuando se convierte explícitamente un Decimal valor en un Double valor mediante C#, C++y Visual Basic. Para realizar una conversión independiente del lenguaje, puede llamar al Decimal.ToDouble(Decimal) método o Convert.ToDouble(Decimal) .

Este operador admite la conversión explícita de a Decimal a .Int64 La sintaxis de estas conversiones explícitas depende del lenguaje y los compiladores de lenguaje individuales pueden proporcionar diferentes implementaciones y devolver resultados diferentes. En el ejemplo se muestran los distintos valores devueltos cuando se convierte explícitamente un Decimal valor en un Int64 valor mediante C# y Visual Basic. Para realizar una conversión independiente del lenguaje, puede llamar al Decimal.ToInt64(Decimal) método o Convert.ToInt64(Decimal) .
