Why isn=E2=80=99t it? I might have learned basic math years ago, but to
me -14013.999999 rounded to one decimal place is exactly -14014.0
(it=E2=80=99s also -14014.00 when rounded to two decimal places, as well as
-14014 when rounded to integers).

> Rounding 9.9 to 10.0 is like rounding 99 to 100

Yeah, but you=E2=80=99re not rounding 9.9 to 10.0 here, you=E2=80=99re roud=
ing
9.99 to 10.0 (which is like rounding 99.9 to 100, i.e., correct).

The reason that every major university maintains a department of
mathematics is that it is cheaper than institutionalizing all those people.

Why isnˇÇt it? I might have learned basic math years ago, but to
me -14013.999999 rounded to one decimal place is exactly -14014.0
(itˇÇs also -14014.00 when rounded to two decimal places, as well as
-14014 when rounded to integers).

Yeah, but youˇÇre not rounding 9.9 to 10.0 here, youˇÇre rouding
9.99 to 10.0 (which is like rounding 99.9 to 100, i.e., correct).
