I have discovered by error something that surprised me.
I have this method
public static string PrintDecimal(decimal? input, string NumberFormat = null){ }
And I call this method like this
int? MaxFaltas = 0;
Label.Text = CustomConvert.PrintDecimal(MaxFaltas);
Why this is working and there are no compilation errors. I'm calling a method witch is defined to receive a decimal?
with a int?
