## Control a loop that uses floating-point values in C#

Sometimes you might need to use a floating-point variable that loop over a range of values. For example, you might want a value to step through the values 0.0 through 1.0 in increments of 0.1. The sequence of numbers would … Continue reading

## Compare floating-point values safely in C#

The computer stores values, including floating-point values, in binary using 0s and 1s. That means it cannot store all possible decimal values exactly. Sometimes when you multiply or divide two floating-point values, the computer is unable to store the result … Continue reading

## Calculate credit payments in WPF and C#

This is a WPF version of the example Calculate credit payments in C#. The calculations are the same. Unfortunately building and using the user interface is much harder in WPF, particularly working with the ListView control. (The unofficial WPF slogan: … 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

## 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
