Challenge for you...

I got 124 zeros, but I used a program "Capture2Text" to ocr your image then put the zeros into a string and then did Print len(a$)

Yeah, I was wanting to check that both strings shown had the same amount of zeros, because the zeros at the top came from my factorial with String math and the ones in the QB64 screen came from David's code which arrived at the result way faster than my String math. 0's are easy to screw up, ask the engineers for Mars Pathfinder Mission (though I think that was a decimal point, about the same difference.)
