Physfit himself never posts to usenet.                     X = 0.9999...       10X = (9 +1)0.9999...       10X = 9(0.9999...) + 0.9999...       after subtraction of first equation from the last one:       10X - X = 9(0.9999...) + 0.9999... - 0.9999...       9X = 9(0.9999...)       X = 0.9999...              Therefore the so called "programmer" of HelloFresh company creating that       test to check whether a robot was ordering or a human, was just a "code       monkey" mistakenly hired as a real programmer.              But back to what Kosmanson was saying. My question was whether       Kosmanson's concern applied to the fact that 10 times 0.9999... is       really not 9.9999... Cause it's really not 9.999... !              --- SoupGate-DOS v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
