I-Calculator yokujikelezisa

Iqoqa inani kunoma yiliphi inani lezindawo zesibalo, phezulu noma phansi.

Izinhlamvu zesithupha (noma ama-digits abalulekile). Sebenzisa i-0, noma inani elilahlekile, ukujikeleza izikhulu/amakhulu.
I-Rounded (ephakathi) —
Iqoqwe —
I-Rounded down —
Ihlukaniswe (ihlukaniswe) —

Iziphetho zivuselelwa uma ubhala.

Malunga nale khadi

the standard rounding, the value is rounded to the digit just past the cut-off — 5 or more rounds up, less than 5 rounds down — so 3.14159 to two decimal places is 3.14. The other columns force a direction: for 2.673 the nearest and floor both give 2.67 while the ceiling gives 2.68, and truncation simply drops the extra digits to the left of the point instead, and a negative number of places rounds to −2 places becomes 3

Imibuzo ebuzwa kaningi

Ukuphi ukujikeleza kosuku lokushaya isiphetho?

Bona inani elidlulele ku-cut-off: 5 noma ngaphezulu okujikelezayo phezulu, ngaphantsi kwe-5 okujikelezayo ngezansi. 3.14159 endaweni ezimbili yi-3.14.

Yini okwenziwa yinombolo e negalelo yezindawo zesibalo?

Ijikelezisa ekhohlo kwengxenye yeshumi: -1 ijikelezisa ku-10 ephakathi, -2 ku-100 ephakathi. 3457 kuya -2 amakheli yi-3500.

Yini ushintsho phakathi kokujikeleza phezulu nokujikeleza ngezansi?

Ukujikeleza phezulu (i-ceiling) nsuku zonke kuhamba ku-value enkulu futhi kujikeleza ngezansi (i-floor) kuncane, ngenkathi okuncane kuthatha okuncane. Ku-2.673 endaweni ezimbili, okuncane nokuncane kunikeza 2.67 kodwa phezulu kunikeza 2.68.

Yini okubonisa imiphumela eqoshiwe?

Icima ama-digits angaphezu kwendawo oyikhethile ngaphandle kokujikelezisa ngaso sonke isikhathi. 2.673 okutholwe iziqongo ezimbili zesibalo yi 2.67, nakuba ukujikelezisa okude kunikeza 2.67 lapha futhi 2.678 kuzotholwe ku 2.67 ngenkathi kujikelezisa ku 2.68.

Ngizoyijikelezisa kanjani inani elibalulekile endaweni yezindawo ezingu-10?

Ushintshe indlela kusuka endaweni yeshumi kuya kumanani abalulekile. Ukucaciswa kwe-3 kugcina ama-digits amabili okuqala abalulekile, ngakho-ke 0.0045213 kwenziwa 0.00452.

Ingabe ukujikeleza phezulu kungenza inani likhule?

Kumanani a positif kuphela. Ukujikelezisa phezulu kusho ukujikeleza phezulu ku-positive infinity, ngakho-ke -2.7 kujikeleziswe phezulu kunombolo ephelele yi- -2, okuwubukhulu, hhayi okuncane.
