>> x is een bitwise shift naar rechts.. En die doe je x maal..
Heb je bv een waarde 8 dan is dit binair 1000
8 >> 1 Word dan dus in binair
1000 >> 1 = 0100
Alle bitjes schuiven 1 naar rechts. Dit doe je vaak om bitjes te isoleren zodat je ze afzonderlijk kan gebruiken..
Bij een byte waarde in hex van bv 0xF0 (binair 11110000) en een operatie 0xF0 >> 4 schuif je de bitjes 4 keer naar rechts..
11110000 word dan 00001111 wat hexadecimaal 0x0F is

Je hebt ook naar links en andere botwise operaties.
Wellicht de windows caclulator pakken en op programmeren mode zetten..
Daar kan je met bitjes schuiven..
