Výpočet sínusu s komentárom od Busyho ---------- Spektrácka kalkulačka RST #28 počíta sínus pomocou polynomického rozvoja. Je to spôsob síce krásny, výsledok dostaneme na 8 až 10 platných číslic, ale veľmi pomalý, pretože je nutné pri ňom urobiť veľa zložitých operácií. Pre demomaking potrebujeme presný opak - výpočet musí byť veľmi rýchly a presnosť nám (obvykle) úplne postačí na osem bitov (v rozsahu 0..255).

multiply-by-32

Anonymous (anonymous@undisclosed.example.com) — 2017-02-16T12:42:16+00:00

Násobenie hodnotou 32 od mikezt ---------- Využíva sa skutočnosť, že 32 je mocnina dvojky a násobenie dvoma je vlastne rotácia doľava. Samotné násobenie 32 je teda rotácia doľava o 5 pozícií. Ak sa ale zamyslíme, môžeme využiť vlastnosť, že rotácia o 8 pozícií doľava je nastavenie vyššieho bajtu nižším a nižšieho nulou. Potom spravíme 3 rotácie doprava (delenie dvoma), a získame naše očakávané násobenie 32. Príklad:
