Hej Wagner Lipnharski. Tack fšr ditt meddelande 14:13 000412 -0400 enligt nedan: >Well, did you ever found a bug in a pocket calculator? Yes - Scary. It was a programmable pocket calculator i had in school, SHARP PC-512 or something. I got teh wrig answer to an equation. Friends tried to help, and we got different answers to the same equation. We split it up and fond it did wrong in some combination of numbers in a simple division, like 27/3 dit not become nine or something like that. Strangely one of my class friends had exactly the same SHARP model number, and it did calculate exactly. The manufacturer did not want to change the model number, but one thing they did to make a differense was: the corrected version had another color of the back plate. Never trust a machine, program, or human too, for that sake... /Morgan
