Use the BigInteger structure in C#
The long data type can hold values between roughly 9.2 x 1018 and 9.2 x 1018, but sometimes even that range isn’t big enough. The .NET Framework 4.0 (C# 4.0 or Visual Studio 2010) introduced the BigInteger structure to represent … Continue reading

Use “banker’s rounding” and “normal rounding” in C#
By default the Math.Round method uses “banker’s rounding.” In banker’s rounding a number with a final digit of 5 is rounded to the nearest even number rather than to the next larger number as you might expect. The idea is … Continue reading
Define and use bit masks in C#
The example Understand bit masks in C# explains how to use bit masks. To define a bit mask, simply create an enum and give it the Flags attribute as in the following code. [Flags] private enum BitmaskEnum { Value1 = … Continue reading
Understand bit masks in C#
Some values, including some properties defined by the .NET Framework, are bit masks. That means each bit in a value means something. For example, the AnchorStyles enumeration that determines how controls are anchored in their parents defines four values: Top, … Continue reading
Use bit operations in C#
C# defines several operators that perform bit operations. As you may be able to guess from the names, these operators manipulate the bits in an integer value. They operate on the value’s bits separately so they are sometimes called “bitwise … Continue reading

Compare speeds of arithmetic operations in C#
This example compares the speeds of arithmetic operations with different data types. There’s a big difference between the speeds of operations using the decimal data type and the other types, so performing a loop a certain number of time is … Continue reading

Make a stacked graph showing compound interest in C#
The example Show compound interest graphically in C# displays a graph showing contributions, compound interest, and total balance over time for a monthly investment strategy. This example may provide a better representation than that one. It shows the total contributions … Continue reading
Show compound interest graphically in C#
This is a more graphic version of the example Calculate the value of a monthly investment in C#. Instead of adding values to a ListView control, this example saves points in three lists of points: Balance, Contributions, and Interest. It … Continue reading
Calculate the value of a monthly investment in C#
The magic of an investment with compound interest is that, over time, you get interest on the interest. For each month this program calculates the interest on the account balance. It then adds the interest and a monthly contribution to … Continue reading
