#bitmanipulation — Public Fediverse posts

Gestern ist das Buch mit den Bitzaubersprüchen angekommen. Da muss man als Softwareentwickler einfach mal drin schmökern. Bevor es verboten wird, weil derartiges Wissen nur noch der KI vorbehalten ist.🤣

Da stehen ohne Ende so Sachen drin wie:

"Use the following formula to turn off the rightmost 1-bit in a word, producing 0 if none (e.g., 01011000 01010000):
x & (x – 1)"

Wobei x ein 32Bit-Wert ist.
