Any computer? You're apparently unaware that there are decimal-based
digital computers. Heck, old mechanical adding machines were decimal
computers. And not by any software either. There's arbitrary precision
software that handles decimal arithmetic.

What you should have written was Excel and any other software that
uses binary floating point arithmetic.
