Problem 52609. Easy Sequences 11: Factorial Digits without Trailing Zeros

Here is an easy one...
It is not difficult to count the number of digits of the factorial of a given number. For example for 'n = 10', we have:
>> length(num2str(factorial(10)))
>> ans =
7
But 2 of those digits are just trailing zeros. So, for 10!, if we remove the trailing zeros, there would only be 5 digits left.
Write a function that outputs the number of digits of factorials excluding trailing zeros.
