Amanani a-rational
Kwi mathematika, irational number lilo naliphi na  inani elinokubizwa ngokuba yiquotient okanye yifraction p/q yee integer ezimbini,  up no q, libe linedenominator engu-q engalinganiyo no-zero. kuba ke u-q esenokulingana no- 1, yonke i-integer iba linani eli-rational. Ingqokolela yawo onke amanani a-rational ihlala ibonakalisa ngobhalo ongqindilili u Q (okanye  umbhalo obhalwe ngqindilili kwibhodi emnyama , i-Unicode ); wamiselwa ngo-1895 nguPeano emva kwe quoziente, igama lesiTaliyane elithetha i"quotient".

I- decimal expression ye-rational number isoloko inokuphelelwa emva kwenani lokugqibela kuludwe lwamanani okanye iqalise ukuphinda-phinda kwa olo ludwe lolandelelwano kwinani lokugqibela loo nto isenzeka ngokuya isenzeka ngokuphundaphindeneyo. Ngaphezu koko, naluphi na uphinda-phindo okanye ukupheliswa kwe-decimal kumele inani eli-rational. Ezi zivakalisi ziyinyaniso, kodwa zingeyonyaniso yebase 10 kuphela, kodwa zikwayinyaniso yayo nayohi na enye i-integer base (umzekelo ibinary, ihexadecimal).

I real number engekho rational ibizwa ngokuba yi-irrational. Amanani azii-iIrrational aquka , π, e, kunye neφ. I-decimal expansion yenani eli-irrational iyaqhuba ingaphindwa-phindwanga.  Kuba ingqokolela yamanani a- rational numbers  ikwazi ukubaleka countable, ibe yona ingqokolela yamanani angawo  (iireal numbers)  ingenakho ukuba ingabalwa, phantse onke ii-real numbers zi-irrational.
