**Is exp(pi * sqrt (163)) odd or even? **

**Abstract:**In fact, the number from the title is not an integer, but it is amazingly (up to twelve digits) close to being one, and the reasons for it are not so apparent. We will look deeper into this "coincidence", and will briefly discuss how different areas of mathematics (complex analysis, elliptic curves, number theory) are needed to fully understand it.
