Math.PI values are inconsistent

[ladeak]

Documentation says at the top:
public const double PI = 3.14159265358979;

In the remarks

The value of this field is 3.1415926535897931.

While in the source it is really this value:

public const double PI = 3.14159265358979323846;

And just too add more to it:

> Console.WriteLine(((Math.PI - 3.14159265358979)) > Double.Epsilon)
True
> Console.WriteLine(((Math.PI - 3.141592653589793)) > Double.Epsilon)
False
