  • A simple way is you create a variable of type decimal to receive these values and when presenting them you use the function ToString(), looks something like this: variable declaration decimal numero = 0; attribution of the value to it numero = 1.33M; obtaining the rounded value: MessageBox.Show(numero.ToString("N1")); //Resultado: 1,3, another example: numero = 1.35M; outworking: MessageBox.Show(numero.ToString("N1")); //Resultado: 1,4
