Umsebenzi we-Rounding (Rnd)

Impikiswano yalokhu kusebenza yenziwa inani ledesimali bese

ijikeleziswe ngokufanele ngenombolo yamanje yokubonisa isethingi

lamadijithi (Norm, Fix, noma Sci).

Nge-Norm 1 noma i-Norm 2, impikiswano ijikeleziswa ngokwezinombolo

zamadijithi angu-10.

Nge-Fix nange-Sci, impikiswano ijikeleziswa ngokwamadijithi abaluliwe.

Uma u-Fix 3 eyisethingi lamadijithi abonisiwe, ngokwesibonelo,

umphumela ka-10 ÷ 3 uzoboniswa njengo-3,333, kuyilapho umshini

wokubala ugcina inani lika-3,33333333333333 (15 amadijithi) ngaphakathi

mayelana nesibalo.

Esimweni lapho u-Rnd(10÷3) = 3,333 (ngo-Fix 3), kokubili inani

elibonisiwe nenani elingaphakathi lomshini wokubala kuzoba ngu-3,333.

Ngengxa yalokhu, uchungechunge lwezibalo luzokhiqiza imiphumela

ehlukile kuye ngokuthi u-Rnd usetshenzisiwe yini (Rnd(10÷3) × 3 = 9,999)

noma cha (10 ÷ 3 × 3 = 10,000).

Isibonelo: Ukwenza izibalo ezilandelayo lapho u-Fix 3 ekhethiwe

ngokwenombolo yamadijithi aboniswayo: 10 ÷ 3 × 3 ne-Rnd(10 ÷ 3) ×
