Uhlobo lokuguqulwa. ImiSebenzi yoPhuhliso kunye neTrunc kwi "Pascal"

Ukusebenza ePascal ngeentlobo ezahlukeneyo zeentlobo ezahlukeneyo, ngokuqhelekileyo kufuneka sijongane nelokuba xa kuqulunqwa inkqubo kukho iiphoso ezibonisa ukuguqulwa kwamanani. Ngokomzekelo, awukwazi ukunika i-variable variable ye-5.9, kuba oku kuya kubangela iphutha lokuhlanganiswa. Kule meko, kufuneka uxoxe ngokusebenzisa imisebenzi ye-Round and Trunc e-Pascal, apho unokuguqula iindidi zeengxabano uze uqhubeke ukwenza imisebenzi ethile kunye nabo.

Ulwazi olubanzi malunga nokuguqula uhlobo

Uhlobo lokuguqulwa (ukunciphisa amaxabiso) yinkqubo yokuguqula ixabiso lenye uhlobo lwedatha kwenye. Kukho iifayile ezicacileyo kunye nokukhangela. Iyokuqala isetyenziswe ngqo ngumbonisi usebenzisa iilwimi ezakhiwayo okanye ukusebenzisa imisebenzi, kwaye okwesibini yenziwa ngokuzimela ngenguquliki okanye ikhowudi iqulunqa ngokwemiqathango echazwe kumgangatho wolwimi oluthile lwenkqubo.

Uhlobo lokuguqula kwi-Pascal

Kwilwimi yePaccal yolwimi, ungasebenzisa ukuguqulwa kohlobo olucacileyo kunye olucacileyo.

Ngokugxilwa ngokucacileyo, uPascal usebenzisa iifowuni kwimisebenzi yokuguqulwa ekhethekileyo apho iingxabano zoluhlobo olufanayo, kunye nexabiso lentlobo eyahlukileyo yedatha. Ezi zi Umsebenzi we-Trunc kumsebenzi we-Pascal kunye no-Round, oza kuxoxwa ngawo ngeenkcukacha ezingezantsi.

Ukukhishwa ngokuthe ngqo kweentlobo kulwimi kunokwenzeka kuphela kwiimeko apho kubhalwe khona amagama Iinguqu ezininzi kunye nezingokoqobo, zangaphambili ziguqulwa ngokuzenzekelayo zibe luhlobo lwesibini.

Emva koko, siya kuthetha malunga nendlela onokuphumeza ngayo ukukhwa kwefayile yedatha yenombolo.

Trunc

Umsebenzi wokwakha wemathematika. I-Trunc e "Pascal" ilahla yonke inxalenye yeengxabano, iholele ekuboneni kwenani elipheleleyo. Umzekelo, ngokubiza umsebenzi I-Trunc kunye neengxabano (1.73) ekugqibeleni ungafumana umphumo 1.

Syntax : Imisebenzi : Trunc (X: yangempela): Ixesha elide.

Ujikeleze

Umsebenzi wokwakha wemathematika. Umsebenzi ojikelezayo ujikeleza ingxabano ngokwemiqathango yemathematika kwi-integer esondeleyo. Umzekelo, ukubiza iNkquthela (1.73) kuya kugqiba nge-2, kwaye ujikeleze ukusuka kwingxabano (1.11) iya kunika 1.

функции : Umsebenzi we- syntax : Ujikeleze (X: yangempela): Ixesha elide.

Kubalulekile ukuba uqaphele ukuba kukho ukunciphisa kwimiphumo yemisebenzi ye-Round and Trunc ePascal. Ukuphunyezwa kuya kuphumelela xa oku kuphumela Ihamba ngaphaya kwexabiso lohlobo olude.

Ngokucacileyo, i-syntax yomsebenzi owenziweyo ilula kwaye ikuvumela ukuba usebenzise i-Round and Trunc e-Pascal ukuze uguqule ngokucacileyo uhlobo ngaphandle kweengxaki ezingadingekile kwaye kungabangela ukuphosakela kokuhlanganiswa malunga nokuphulwa kohlobo.
