# What is the best datatype for money in C# and VB.NET

The best Datatype for money in C# and VB.NET is Decimal.
What is the MSDN saying about Decimal.

The Decimal value type represents decimal numbers ranging from positive 79,228,162,514,264,337,593,543,950,335 to negative 79,228,162,514,264,337,593,543,950,335. The Decimal value type is appropriate for financial calculations requiring large numbers of significant integral and fractional digits and no round-off errors. The Decimal type does not eliminate the need for rounding. Rather, it minimizes errors due to rounding.

# How to round to X decimal places in C# and VB.NET

To round to X decimal places in C# and VB.NET you can use one of the following methods.
Take a look at the output image to see the results.

## Sample ConsoleApp in C#

```static void Main(string[] args)
{
decimal input = Decimal.Parse("3,546932");
decimal inputZero = Decimal.Zero;
decimal inputShort = Decimal.Parse("3,545");
decimal inputShorter = 1;

Console.WriteLine("######################################################################");
Console.WriteLine("");
Console.WriteLine("Testinput1:\t{0}", input);
Console.WriteLine("Testinput2:\t{0}", inputZero);
Console.WriteLine("Testinput3:\t{0}", inputShort);
Console.WriteLine("Testinput4:\t{0}", inputShorter);
Console.WriteLine("");

Console.WriteLine("########## using decimal.Round AwayFromZero 2 Decimals ##########");
Console.WriteLine("");
Console.WriteLine("Output 1:\t{0}",decimal.Round(input, 2, MidpointRounding.AwayFromZero));
Console.WriteLine("Output 2:\t{0}", decimal.Round(inputShort, 2, MidpointRounding.AwayFromZero));
Console.WriteLine("Output 3:\t{0}", decimal.Round(inputShorter, 2, MidpointRounding.AwayFromZero));
Console.WriteLine("Output 4:\t{0}", decimal.Round(inputZero, 2, MidpointRounding.AwayFromZero));
Console.WriteLine("");

Console.WriteLine("########## using decimal.Round ToEven 2 Decimals ##########");
Console.WriteLine("");
Console.WriteLine("Output 1:\t{0}", decimal.Round(input, 2, MidpointRounding.ToEven));
Console.WriteLine("Output 2:\t{0}", decimal.Round(inputShort, 2, MidpointRounding.ToEven));
Console.WriteLine("Output 3:\t{0}", decimal.Round(inputShorter, 2, MidpointRounding.ToEven));
Console.WriteLine("Output 4:\t{0}", decimal.Round(inputZero, 2, MidpointRounding.ToEven));
