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
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
