Use digits of Pi to draw a picture in C#

Posted on March 15, 2017 by RodStephens

The article 10 stunning images show the beauty hidden in pi shows several ways to use Pi to generate pictures. This example demonstrates one of them. The program starts drawing at the origin (0, 0). It then scans through the … Continue reading →

Find patterns within Pi in C#

Posted on March 14, 2017 by RodStephens

March 14 is known as Pi Day because its numeric representation 3/14 includes the first three digits of Pi: 3.14. (At least in the United States. In Europe where they usually write dates month first, Pi Day is July 22 … Continue reading →

Use the Obsolete attribute in C#

Posted on June 3, 2016 by Rod Stephens

The Obsolete attribute tells the C# IDE that a method is outdated and should no longer be used. You can include a string to display to the developer. The string usually tells what newer method to use instead of the … Continue reading →

Approximate pi using several different methods in C#

Posted on March 16, 2015 by RodStephens

The post In honor of Pi Day (3.14), approximate pi in C# uses the following sequence to approximate pi. That sequence is elegant but unfortunately it converges very slowly so you need to take a lot of terms to get … Continue reading →

Graph pi approximations in C#

Posted on March 15, 2015 by Rod Stephens

My post In honor of Pi Day (3.14), approximate pi in C# uses the following series to approximate the value π. As you add terms to the series, the approximation alternates between values that are above and below the true … Continue reading →

In honor of Pi Day (3.14), approximate pi in C#

Posted on March 14, 2015 by Rod Stephens

There are several ways to calculate π. Many use an infinite series such as the following one. This isn’t necessarily the best series to use, but it is relatively simple. When the program starts, it uses the following code to … Continue reading →
