Number of digits of n!
In this video, I used the definition of logarithm and the factorial for real numbers to obtain the number of digits of any factorial. In particular, I found the number of digits for 1000!. The formula was adjusted to use the mid Reimann sum. I have not tested every number for this formula but It worked for the ones I tested. Please leave a comment in the comment section.
