Explicație pas cu pas:
17,250 aprox la unitate in plus 18
...........................................in minus 17
................................zecime in plus17,3
...............................................in minus 17,2
...................sutime in plus nu are sens nrse termina la sutime raman17,25
..................................sutime in minus......................................idem 17,25
miimi nu are sens, numarul nu are miimi
123,076.............unitate in plus 124 ...in minus 123
zecime in plus 123,1 ...in minus 123
sutime in plus 123,08....in minus 123,07
miime nu are sens aproximarea, numarulse termina exact la miime...123,076
4123, 9781........unitate in plus 4124.......in minus 4123
zecime......in plus 4124 (mai maredecat 9 zecimi si ceva sunt 10 zecimi...adicva unitatea).in minus 4123,9
sutimi.in plus 4123,98.....in minus 4123,97
miimi, in plus 4123,979.........in minus 4123,978 9 am taiat zecimea de miime, deci am aproximat in minus)
