Dziwani kuti zotsatira za kuchita ntchito Trunc ndi Round mu "Pascal" ali ndi zofooka. Akuphedwa adzalephera ngati chotsatirachi Iwo akupita kupyola mtundu Longint phindu.

N'zoonekeratu kuti malembedwe a ntchito onse anamanga-ndi wosavuta ndipo angagwiritsidwe ntchito mu Round ndi Trunc "Pascal" kwa olaula mtundu kutembenuka popanda mavuto ena ndi zimayambitsa kulemba zolakwa za mitundu kuphwanya.
