Izibonelo zezinombolo ezingenangqondo

Lapho sikhuluma "ngezinombolo" sibhekisa kuleyo miqondo yezibalo leyo imele inani elithile maqondana neyunithi. Kulezi zinkulumo zezibalo izinombolo ezinengqondo nezingenangqondo ziyakhonjwa:

Kunengqondo: Uma sikhuluma ngalezi zinombolo sibhekisa kulezo ezingabonakaliswa njengengxenyenamba, enesingenezo esingelona uziro. Ngokuyinhloko i-quotient yezinombolo ezimbili ezingama-integer.
Akunangqondo: Ngokuphikisana nezinombolo ezinengqondo, lezi azikwazi ukuvezwa njengengxenyenamba. Lokhu kungenxa yokuthi zinamanani wedesimali angewona ama-periodic ngokungapheli, noma ngokungapheli. Lolu hlobo lwezinombolo lukhonjwe ngumfundi wasePythagoras, owaziwa ngegama likaHipaso.

pi (pi): Le mhlawumbe yinombolo engenangqondo eyaziwa kunazo zonke. Kungukuvezwa kobudlelwano obukhona phakathi kobubanzi besigaba nobude baso. I-Pi bese kuba ngu-3.141592653589 (…), noma ngabe yaziwa ngokujwayelekile njenge-3.14.
√5: 2.2360679775
√123: 11.0905365064
futhi: Yinombolo ye-Euler futhi ijika elibonwa kwizicubu zikagesi futhi elivela ezinqubweni ezifana nemisebe enemisebe noma ezinqubeni zokukhula. Inombolo ka-Euler ithi: 2.718281828459 (…).
√3: 1.73205080757
√698: 26.4196896272
Igolide: le nombolo, emelwe ngophawu olulandelayo Φ, okungeyona enye into ngaphandle kohlamvu lwesiGreki u-Fi. Le nombolo yaziwa nangokuthi i- isilinganiso segolide, inombolo yegolide, kusho, isilinganiso segolide, phakathi kwabanye. Okuvezwa yile nombolo engenangqondo isilinganiso esikhona phakathi kwezingxenye ezimbili zomugqa, kungaba okuthile okutholakala empeleni noma isibalo sejometri. Kepha ngaphezu kwalokho, inombolo yegolide isetshenziswa kabanzi ngabaculi ababukwayo lapho besungula ubukhulu emisebenzini yabo. Le nombolo ithi: 1.61803398874989.
