It is 11900.

Most schools teach you to always round 5 up (to 11910). However, doing so is inappropriate because it introduces an upward bias. The IEEE (Institute of Electronic and Electrical Engineers) standard 754 is to round 5 up or down so that the new last digit is even.

It is 11900.

Most schools wrongly teach you to always round a half up (so the answer would be 11910) but, while this is a simple rule to teach, it is not really correct. Under this rule:

  • if the following digit is 0 you don't round;
  • if the following digit is 1, 2, 3 or 4 you round down; and
  • if the following digit is 5, 6, 7, 8 or 9 you round up.

As a result you are more likely to round up than round down and that introduces an upward bias into your calculations.
