Both the 7.8 and the 7.7 are actually 7.75mm, exactly the same dimension. Why is it rounding one up and one down? Also some screenshots included of relevant document properties:
i just did a test with one dimension as 7.75 and another as 7.749 and got the same result as seen in Sjoerd van De Velde's image. and when i set the decimal places to 2 they both show 7.75
Show all decimal and see if they're really the same.

Thanks... annoying, I tried this before posting my question with 3 decimals, it shows 7.75 and 7.75.. Only when it set it to 4 decimals it shows a difference: 7.7501 and 7.7499.
Am I misunderstanding rounding here? When rounding you look at the next digit only. So when rounding to 1 decimal place you only look at the second decimal place. In this case:
7.74 = 7.7
7.75 = 7.8
I don't know, maybe they're teaching that differently now...
it is doing exactly what it should. when rounding 7.74 to one decimal place the 7 remains unchanged. when rounding 7.75 to one decimal place the 7 becomes 8. just because 7.7499 rounded to 3 decimal places makes it 7.750 doesn't mean that 7.7499 rounded to 1 decimal place should be 7.8. it's not going to round an already rounded number it is going to round the original value.
I agree, but over at 8 ÷ 2(2+2)= some of these youngsters seem to be doing math differently now...
It reflects the proper way, your model is wrong (my guess)
