Here is a little Linqpad program to show different formats:

void Main()

    FormatDecimal(2345.94742M);

    FormatDecimal(0.007M);
}

public void FormatDecimal(decimal val)
{
    Console.WriteLine("ToString: {0}", val);
    Console.WriteLine("c: {0:c}", val);
    Console.WriteLine("0.00: {0:0.00}", val);
    Console.WriteLine("0.##: {0:0.##}", val);
    Console.WriteLine("===================");
}

Here are the results:

ToString: 2345.94742
c: $2,345.95
0.00: 2345.95
0.##: 2345.95
===================
ToString: 43
c: $43.00
0.00: 43.00
0.##: 43
===================

c: $0.00
0.00: 0.00
0.##: 0
===================
ToString: 0.007

0.00: 0.01
