This can be done through the use of the number object’s ToString() method. A common practice is printing out mathematical operations with the use of the ToString() method on the double object. What usually happens is the printing of a long string containing all the decimal places existing in the double. This sometimes makes output cluttered and hard to read. Luckily, C# has a robust set of string formatting options available to make the string more comprehendible. Here is a list of common formatting options available in the ToString() method: Code: ```double c = 10.25693; Print("No formatting: " + c.ToString()); Print("Currency formatting: " + c.ToString("C")); Print("Exponential formatting: " + c.ToString("E")); Print("Fixed-point formatting: " + c.ToString("F2")); Print("General formatting: " + c.ToString("G")); Print("Percent formatting: " + c.ToString("P0")); Print("Formatted to 2 decimal places: " + c.ToString("N2")); Print("Formatted to 3 decimal places: " + c.ToString("N3")); Print("Formatted to 4 decimal places: " + c.ToString("N4"));``` The corresponding output is as follows: Code: ```No formatting: 10.25693 Currency formatting: \$10.26 Exponential formatting: 1.025693E+001 Fixed-point formatting: 10.26 General formatting: 10.25693 Percent formatting: 1,026 % Formatted to 2 decimal places: 10.26 Formatted to 3 decimal places: 10.257 Formatted to 4 decimal places: 10.2569``` For custom formatting you can use the following: Code: ```double phoneNumber = 9162031022; Print("Phone number: " + phoneNumber.ToString("(###) ### - ####"));``` Corresponding output: Code: `Phone number: (916) 203 - 1022` For more information on general string formatting this guide may be of use.

CFTC Rules 4.41 - Hypothetical or Simulated performance results have certain limitations, unlike an actual performance record, simulated results do not represent actual trading. Also, since the trades have not been executed, the results may have under-or-over compensated for the impact, if any, of certain market factors, such as lack of liquidity. Simulated trading programs in general are also subject to the fact that they are designed with the benefit of hindsight. No representation is being made that any account will or is likely to achieve profit or losses similar to those shown.
