I think this goes back to the 1980s, when all of this was true. Xor ax,ax was faster than setting ax to 0. The system random() call slowly delivered alternating odd and even numbers, all located on n-dimensional hyperplanes.
Nadhani hii inakwenda nyuma miaka ya 1980, wakati haya yote yalikuwa kweli. Xor shoka, shoka mara kwa kasi zaidi kuliko kuweka shoka kwa 0. mfumo random () kuwaita polepole mikononi alternating idadi isiyo ya kawaida na hata, kila ziko kwenye hyperplanes n-dimensional.
