Default Use the digits from 0 through 9

Can you use the digits from 0 through 9 - using any of the four operations, addition, subtraction, multiplication and division - so that when you do the math you get 100? Each number can be used only once, but you can use them in any order that you like.

Solution:
"(9*8)+(7*2)+(4*3)+6-5+1-0=100"

Is there a formula for calculating the number of digits in a large number?

An example would be 218477
