Pristop s surovo silo
Na primer :
Če je decimalno število 10.
Korak 1 : Ostanek, ko je 10 deljeno z 2, je nič. Zato je arr[0] = 0.
2. korak : 10 delite z 2. Novo število je 10/2 = 5.
3. korak : Ostanek, ko je 5 deljeno z 2, je 1. Zato je arr[1] = 1.
4. korak : delite 5 z 2. Novo število je 5/2 = 2.
5. korak : Ostanek, ko je 2 deljeno z 2, je nič. Zato je arr[2] = 0.
6. korak : 2 delite z 2. Novo število je 2/2 = 1.
korak 7 : Ostanek, ko je 1 deljeno z 2, je 1. Zato je arr[3] = 1.
8. korak : delite 1 z 2. Novo število je 1/2 = 0.
9. korak : Ker število postane = 0. Natisnite matriko v obratnem vrstnem redu. Zato je ekvivalentno binarno število 1010.
Spodnji diagram prikazuje primer pretvorbe decimalnega števila 17 v enakovredno binarno število.
Spodaj je izvedba zgornje ideje.
