Calling log10() on zero causes a non-sensical value to be calculated. On some compile options, I've observed yosys crashing with an illegal instruction (SIGILL). To make it safe, fix the calculation to do a range check; wrap it a decimal_digits() function, and use it where the previous ceil(log10(n)) call was used. As a side, it also improves readability.
