That's an approximation to pi, which is a standard floating-point value. It's simply 3.141592653589793, nothing more nor less. Infinity is a special floating-point value that actually represents the concept of infinity, not just some huge number. Hence, infinity is special, pi is not. IEEE floating point cannot represent pi, the square root of 2, or i, but it can represent infinity and nan, so there need to be ways to create those. ChrisA
