Izinzuzo Zokusebenzisa Izinombolo Eziphelele
Ama-Integer angomunye wemibono eyisisekelo kakhulu kwizibalo, ahlanganisa izinombolo ezingezinhle, u-zero, kanye nezinombolo ezinhle. Empilweni yansuku zonke, sivame ukubhekana nama-integer ngaphandle kokuqaphela, isibonelo lapho sibala izinto, sinquma inani lezitezi esakhiweni, siqopha izinguquko zokushisa, noma sibala inzuzo nokulahlekelwa ebhizinisini. Ngenxa yemvelo yazo elula kodwa enamandla, ama-integer ayithuluzi elibalulekile lokuqonda, ukulinganisa, nokwenza izinqumo. Lesi sihloko sizoxoxa ngezinzuzo ezahlukahlukene zokusebenzisa ama-integer emikhakheni nasezimweni ezahlukahlukene.
1. Kwenza Izibalo Zibe Lula Empilweni Yansuku Zonke
Inzuzo esobala kakhulu yama-integer ukuthi kulula ukubala. Awabandakanyi izingxenyana noma ama-decimals, okwenza imisebenzi efana nokuhlanganisa, ukususa, ukuphindaphinda, kanye nokuhlukanisa (ezimweni ezithile) isheshe futhi ibe lula.
Isibonelo esilula ukuthenga. Uma sithenga izinkwa ezintathu bese sengeza ezimbili, ingqikithi yizinkwa ezi-5. Akukho ukungabaza noma ubunzima esingase sibhekane nabo lapho sibhekene nezingxenyana. Ngokufanayo, lapho sibala inani labafundi ekilasini, inani lezihlalo, noma inani lezimoto ezidlulayo, izinombolo eziphelele ziyisinqumo esinengqondo kakhulu ngoba izinto ezibalwayo ziphelele.
2. Kusiza ekuchazeni ngokucacile imiqondo “encane” kanye “neningi”.
Izinombolo eziphelele zinezinhlangothi ezinhle nezimbi, okwenza zibe usizo ekuchazeni izimo "eziningi" nezincane ngendlela elula ukuyiqonda. Isibonelo, esimweni sezezimali, inombolo enhle ingabonisa inzuzo noma ibhalansi, kuyilapho inombolo engemihle ikhombisa ukulahlekelwa noma isikweletu.
Uma umuntu enebhalansi engu-Rp50.000, ingabhalwa njengo-+50.000. Uma ekweleta u-Rp20.000, ingabhalwa njengo--20.000. Ngale ndlela, izinombolo eziphelele zinikeza ukumelwa okufushane nokungaguquguquki kwezimo eziphikisanayo. Lokhu kusisiza ukuthi sibheke izimo ngendlela engathathi hlangothi futhi kwenze izibalo zihleleke kakhudlwana.
3. Iwusizo Ekulinganiseni Izinga Lokushisa Nokuphakama
Ama-Integer nawo awusizo kakhulu kwisayensi, ikakhulukazi ekulinganiseni izinga lokushisa kanye nokuphakama. Ezikalini zokushisa ezifana ne-Celsius, sivame ukuthola amazinga okushisa angaphansi kuka-zero ebhalwe njengezinombolo ezingezansi. Isibonelo, izinga lokushisa elingu--5°C libonisa izimo ezibandayo kune-0°C.
Ku-geography, ukusetshenziswa kwezinombolo eziphelele kusobala lapho kulinganiswa ukuphakama kwendawo ngaphezu kwezinga lolwandle. Izindawo ezingaphansi kwezinga lolwandle zingavezwa njengezinombolo ezingezinhle, kuyilapho izindawo ezingaphezu kwezinga lolwandle zivezwa njengezinombolo ezinhle. Isibonelo, amamitha angu--10 asho amamitha ayi-10 ngaphansi kwezinga lolwandle. Lokhu kwenza ukufunda idatha kube lula futhi kube nolwazi oluningi.
4. Kusiza ekudalweni kwegrafu kanye nokuhlaziywa kwedatha
Kumathematika kanye nezibalo, izinombolo eziphelele zenza kube lula ukwenza igrafu kanye nokuhlaziywa kwedatha. Umugqa wezinombolo ungenye yezindlela ezilula kakhulu zokubonisa izinombolo eziphelele. Ngomugqa wezinombolo, singaqhathanisa kalula amanani, sibone ukuhleleka, futhi siqonde ubudlelwano phakathi kwezinombolo ezingezinhle nezingezinhle.
Enye inzuzo ukuthi izinombolo eziphelele zivame ukusetshenziswa kumashadi ebha, amathebula emvamisa, kanye nezinye izibalo zamanani ahlukene, njengenani lezehlakalo. Isibonelo, uma isitolo siqopha inani lamakhasimende esikhathini sezinsuku eziyi-7, idatha eqoshiwe ngokuvamile ingaba izinombolo eziphelele: amakhasimende ayi-120, amakhasimende ayi-135, amakhasimende angama-98, njalo njalo. Idatha ephelele kulula ukuyiphatha, ukuyiqoqa, nokuyihlaziya ukuze kwenziwe izinqumo.
5. Izisekelo Ezibalulekile Zokuqonda Izibalo Ezithuthukisiwe
Ama-integer akha isisekelo semiqondo yezibalo eyinkimbinkimbi kakhulu. Ukuqonda kahle ama-integer kusiza abafundi ukuthi bafunde izihloko ezifana nama-fraction, ama-decimals, amaphesenti, i-algebra, kanye ne-calculus. Isibonelo, ku-algebra, ama-integer avame ukuvela njengama-coefficients, ama-constants, kanye nemiphumela yokusebenza.
Ngaphezu kwalokho, izinombolo eziphelele zifundisa imiqondo ebalulekile njengenani eliphelele, okuphambene, kanye nemithetho yezimpawu ekuphindaphindeni nasekuhlukaniseni. Konke lokhu kuyasiza ekuzijwayezeni ukucabanga okunengqondo kanye nokunemba. Ngamanye amazwi, ukuba yingcweti izinombolo eziphelele akukhona nje ngokubala, kodwa futhi nokwakha amakhono okucabanga ngezibalo.
6. Inendima Enkulu Kwezobuchwepheshe Nakwezekhompyutha
Ekubaleni, izinombolo eziphelele zisetshenziswa kabanzi ukugcina nokucubungula idatha. Izinhlelo eziningi zokubala zisebenza ngezinombolo eziphelele ngoba zisebenza kahle kakhulu kunezinombolo zedesimali, ezidinga ukumelwa okuyinkimbinkimbi kakhulu (iphuzu elintantayo). Isibonelo, inani lokuchofoza, inani lezivakashi zewebhusayithi, izinga lomdlalo, kanye nenkomba ku-array konke kuvame ukusebenzisa izinombolo eziphelele.
Inzuzo yama-integer ekubaleni iyabonakala nasekunembileni kwemiphumela yawo. Izinombolo zamadesimali ngezinye izikhathi zihlushwa amaphutha okuzungeza, kuyilapho ama-integer ehlala enembile inqobo nje uma ehlala ngaphakathi kwemingcele yomthamo wawo wokugcina. Yingakho abahleli bezinhlelo bevame ukusebenzisa ama-integer emisebenzini edinga ukunemba okuphezulu, njengokubala izinto, ukugoqa, kanye nokuhlanganisa idatha.
7. Kusiza Ukwenza Izinqumo Ezimweni Ezihlukahlukene
Izinombolo eziphelele zisiza abantu ukuba benze izinqumo ngokushesha ngoba zinikeza ulwazi olucacile noluqondile. Isibonelo, uma isitoko sento egcinweni sibhalwe njengo-0, kusho ukuthi into ayisekho esitokweni. Uma isitoko sibhalwe njengo-20, kusho ukuthi kunezinyunithi ezingu-20 ezitholakalayo. Lolu hlobo lolwazi luwusizo kakhulu ekuphatheni.
Kwezemidlalo, izinombolo eziphelele zivela kumaphuzu omdlalo: 2-1, 0-0, 3-2, njalo njalo. Ababukeli bangaqonda ngokushesha ukuthi ubani ophumelele. Empilweni yokuhlela, izinombolo eziphelele zisetshenziselwa ukubala inani lamavoti okhethweni: amavoti ayi-120 avumelanayo, amavoti angama-30 aphikisanayo. Umphumela ucacile futhi kulula ukuwuchaza.
8. Kunciphisa Ubunzima kanye Nengozi Yephutha
Ngenxa yokuthi izinombolo eziphelele azibandakanyi izindawo zamadesimali, ukuzisebenzisa kunganciphisa ingozi yamaphutha okubala ezimweni ezithile. Ezimweni eziningi, ukusebenzisa izinombolo eziphelele kuphephile, ikakhulukazi uma idatha ebalwa inamayunithi aphelele. Amaphutha amancane kumadesimali angaba nomthelela omkhulu ezinqumweni, kuyilapho izinombolo eziphelele zivame ukuzinza kakhulu ekubaleni okulula.
Isibonelo, lapho sibala inani lezihlalo ezidingekayo emcimbini, singase singadingi izihlalo eziyi-10,5. Ukukhetha okunengqondo kungaba yi-10 noma i-11. Ukusebenzisa izinombolo eziphelele kwenza ukuhlela kube ngokoqobo futhi kube lula ukukusebenzisa.
Isiphetho
Ama-integer anezinzuzo eziningi ezenza abaluleke kakhulu empilweni yansuku zonke kanye nasemikhakheni eyahlukene yesayensi. Kusukela ekusizeni ukubala okulula, ukuchaza izimo zenzuzo nokulahlekelwa, ukukala izinga lokushisa kanye nokuphakama, kuya ekusekeleni ubuchwepheshe bekhompyutha, ama-integer adlala indima ebalulekile ekwenzeni lula umsebenzi womuntu. Ngaphezu kwalokho, ama-integer ayisisekelo sokuqonda okubanzi kwezibalo. Ngokuqonda nokusebenzisa ama-integer ngendlela efanele, singacabanga ngendlela ehlelekile, sisebenze kahle kakhulu, futhi senze izinqumo ezingcono ezimweni ezahlukahlukene.
