This node is not about 163. Nor is it about sqrt(163), or even sqrt(163)*pi. All those numbers are completely useless. It's about exp(sqrt(163)*pi). Amazingly enough, this number is not an integer!!(!)

Watch GNU bc tackle the problem (input lines are preceded by "⇒", which bc doesn't do naturally)
