Amanye amanani a-rational (ii-rational numbers), afana no-1/10, zidinga inani eli-finite (i-finite number) lee-digits emva kwe-decimal point ukuze abhalwe ngendlela e-decimal. Ishumi lokuqala (ebizwa ngokuba yi-number one tenth, ngesiNgesi) ibhalwa ngokwe-decimal ibe ngu-0.1. Amanani abhalwe ngokwendlela ye-finite decimal ngala aba-rational. Amanye amanani a-ratiinal (azi-rational numbers), afana no-1/11, adinga inani eli-finate (i-infinite number) lee-digits emva kwe-decimal point ukuze zibhalwe ngokwendlela ye-decimal. kukho ukuphindaphindwa kwe-pattern yee-digits okulandela emva kwe-decimal point. Inani leshumi elinanye lokuqala (i-number one eleventh) ibhalwa ngendlela ye-decimal eyile 0.0909090909 ... .
