That seems unlikely. Those numbers only look related in base 10. 1/e is about a third of 1 and 37 is about a third of 100, which is why they look similar in base 10. In base 16, 1/e is about 0.5e2d58 and 37 is 25.

And prime numbers are prime numbers regardless of base.

100/e is close to 37, regardless of base.

(That 100 would be chosen as a convenient scaling factor for our notion of “percent” only in base 10 is true, but a separate point.)

[bondarchuk]

No, that is precisely the point.

That's what PP was saying, in not so many words.
