@ruakh oh sorry, I see now.

@vadim123 The probability of picking number with such beginning is not zero. But where is the number, whose picking probability is zero?

@vadim123 so give an example of a number that you picked randomly from 0 to 1.

area zero=probability zero. Not 1. Proportional, not backward proportional. -1

Your example does not prove anything: probability of choosing an integer is zero, AND you never will choose an integer. So probability zero means never happens. Completely wrong answer -1

@nbubis I have re-checked and came to the same result.

@nbubis I also corrected the conclusion: actually there ARE non-trivial solutions, yet the condition does not specify a unique one.

@sun I fixed the typo, thanks. The result does not change, it was only a typo when I copied it here.

comment How to calculate $f(x)$ in $f(f(x)) = e^x$?
Seems this post does not answer the question. The questioner did not look for an entire function and even for funtions on the complex plane at all.

comment The interpretation of $0 \cdot \infty$
You can manipulate $\infty$ in the extended real line. But still for that number multiplication by zero is indefinite.
