If you have 0.245, it is 0.24 rounded to hundreths. How is that '5 goes up?'

If you actually have 0.245, it is 0.25 rounded to hundredths. However,
if you actually have 0.2445, you do NOT have .0245 but a hair less than
that. In that case, you don't =have= a five to "go up".

If you took a big pile of numbers, rounded them all up, added them,
you would have a value that was way off of the true value of the sum.


True. But you don't round them all =up=. You round them all (to the
nearest). Only the ones that are ...5 and up get rounded up. The
others get truncated. Including ...0 which gets its zero truncated
(leaving the number unchanged).

0.247 - 0.25 0.255 - 0.26 is that what you mean? That's exactly what I
stated.


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".
