Nooca diinta. Round iyo shaqada Trunc ee "Pascal"

Ka shaqeynta ah "Pascal" doorsoomayaal of noocyo kala duwan, inta badan u leeyihiin in ay xaqiiqada ah in marka ururinayaan baadi barnaamij ka qaban dhacdaa, taasoo muujinaysa ah qiyamka diinta aan sax ahayn. Tusaale ahaan, ma aad ku wareejin kartid variable ah oo nooca qiimaha abyoonaha ah 5.9, maadaama ay tani keeni doontaa in baadi compiler ah. Xaaladdan oo kale waxaa lagama maarmaan ah in ay ka hadlaan isticmaalka hawlaha Trunc iyo Round ee "Pascal", kaas oo aad ku bedeli karaan noocyada doodaha iyo sii wadaan in ay qabato hawlo gaar ah iyaga.

Warbixin guud oo ku saabsan noocyada diinta

Nooca diinta (qiimaha hoos) - geeddi-socodka ah ee diinta qiyamka mid nooca xogta in kale. Kala shubay toos ah iyo awaamiir. set ugu horeeyay ee si toos ah by sameeysa oo isticmaalaya wax dhista luqadda, ama iyadoo la adeegsanayo hawlaha, iyo tan labaad waxaa lagu fuliyaa si madaxbanaan by compiler ama turjubaan of code xeerarka, ayaa ku dhawaaqay in heerka luqad barnaamijyo gaar ah.

Nooca diinta ee Pascal

In the "Pascal" af barnaamijyada loo isticmaali karaa sida cad ama awaamiir diinta nooca.

Iyada oo noocyo actuation cad "Pascal" waxaa loo isticmaalaa calls for hawlaha diinta ka gaar ah kuwaas oo dood ka tirsan tahay nooca la mid ah, iyo qiimaha - nooc ah oo aad u kala duwan oo xogta. waa kuwa function Trunc ee "Pascal" iyo shaqo Round, kaas oo looga hadli doonaa si faahfaahsan hoos ku.

nooca daama luqadda this ayaa suuragal ah keliya in Xaaladaha ay ku tibaaxaha, taas oo ka kooban abyoonaha oo dhab ah doorsoomayaasha waxaa si toos ah ugu horeysay diinta nooca labaad.

dood soo socda diiradda, sida aad u hirgelin karaan in ay keenaan noocyada xogta tiro.

Trunc

Dhisay-in hawlaha xisaabta. Trunc in "Pascal" iska xoorayaa oo dhan qaybta jajab doodda, isaga oo keentay in tselochiselnomu maanka. Tusaale ahaan, adigoo wacaya Trunc dood (1.73) waxaa laga heli karaa in natiijada dhamaadka waa 1.

Saan : Tilmaamo: Trunc (X: dhabta ah): Longint.

Round

Dhisay-in hawlaha xisaabta. function Round kulminna off Xujada by xeerarka xisaabta lambarka ugu dhow oo dhan. Tusaale ahaan, wacaya Round ah (1.73) ee dhamaadka noqon 2, iyo Round Xujada (1.11) siin 1.

функции : Its Saan waa: Round (X: dhabta ah): Longint.

Waxaa xusid mudan in natiijada fulinta hawlaha Trunc iyo Round ee "Pascal" ayaa xadeynta. Dil gaabnaan doonaa haddaan wax natiijo this Waxaa shaki ka baxsan qiimaha nooca Longint ah.

Waa wax iska cad in Saan labada hawlaha dhisay-in ay tahay wax aad u sahlan oo loo isticmaali karaa in ay Round iyo Trunc "Pascal" for diinta toos ah nooca aan dhibaato dheeraad ah oo sababaha isku ururiso qalad ah oo ku saabsan noocyada xad-gudub.
