Use digits of Pi to draw a picture in C#
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

Look for dates in the digits of Pi in C#
The example Find patterns within pi in C# looks for patterns within the digits of Pi. You can use that example to look for dates such as 4/1. This example determines whether the first 100 thousand digits of Pi contains … Continue reading

Find patterns within Pi in C#
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

Approximate pi using several different methods in C#
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#
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#
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
