( #3333=superdoc: print w/ replies, xml ) Need Help??

  • The first one (9.3333 -> 9.34) is a typo in the original.
  • The second and third one are easily explained by the following
    printf("%.15f", 9.55); # prints 9.550000000000001 printf("%.15f", 43.55); # prints 43.549999999999997
    This means that due to the limitations of the internal representation, the literal 9.55 is in fact 9.550000000000001 which rounds to 9.56. The same goes for 43.55 but there the representation is slightly smaller than 43.55 so a rounding down occurs.
