This is correct rounding, but it is it what George stated. He stated
"round 1/2 to the EVEN number.", which would imply .245 - .26 which is
not true. What =is= true is
.245 - .25
.255 - .26
.265 - .27

This is not "rounding 1/2 to the even number".

Jose, you are with the majority, and you are with what it being taught
in today's schools until higher level mathematics.

The round (exactly) half to the even is correct.

0.2449 - 0.245 - 0.24 - 0.2 but the 0.24 is not for this rule,
rather because the full precision number was under 0.5

0.3499 - 0.350 - 0.35 - 0.3 but again, rule isn't applicable
0.3501 - 0.350 - 0.35 - 0.4 but rule isn't applicable

you have to round from the full precision to the final value in 1
step; the sequential above is interesting, but not as it is done for
the reasons obvious above.

0.5 (exactly) - 0.
1.5 (exactly) - 2.
2.5 (exactly) - 2.
3.5 (again, exactly) - 4

or, fwiw, 1234.5 - 1234. and 1235.5 - 1236.

It used to be taught that way in elementary school, but was changed
between when I went to school (1950s) and when my children went to
school (1990s).

My son has a math degree, and remarked about how higher level high
school and college profs complained about having to correct the
elementaty and middle teachers teaching, but that they taught what
they were given, so it wasn't their fault.
