Malunga nale Calculator
A rounding calculator rounds a number to a chosen number of decimal places (or significant figures) and shows four results side by side: the standard nearest-value rounding, always-up (ceiling), always-down (floor), and truncation, so you can compare every option at once.
Standard rounding looks at 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 2.67 without rounding. Switching the mode to significant figures counts meaningful digits from the first non-zero one instead, and a negative number of places rounds to the left of the point, so 3457 to −2 places becomes 3500.
Rounding matters for money, measurements, reporting to a sensible precision, and avoiding false accuracy in results. Seeing nearest, up, down and truncated together makes it clear how much a value shifts depending on which rule you apply.
Imibuzo ebuza rhoqo
Ujikeleziso lweendawo zeshumi lusebenza njani?
Bona umlinganiselo odlulayo kwi-cut-off: 5 okanye ngaphezulu kokugquma phezulu, ngaphantsi kwe-5 kokugquma ezantsi. 3.14159 ukuya kwiindawo ezimbini yi-3.14.
Yintoni eyenza inani elilahlekileyo leendawo zeshumi?
Ijikelezisa ekhohlo kwenqaku leshumi: -1 ijikelezisa kwishumi elifutshane, -2 kwikhulu elifutshane. 3457 ukuya -2 iindawo yi-3500.
Yintoni utshintsho phakathi kokujikeleza phezulu nokuhamba phantsi?
Ukujikelezisa phezulu (i-ceiling) kuhlala kuhamba kwixabiso elikhulu kwaye kujikelezisa ezantsi (i-floor) kuncinci, ngelixa okufutshane kuthatha okufutshane. Kuba yi-2.673 kwiindawo ezimbini, okufutshane nokuphantsi kunika i-2.67 kodwa phezulu kunika i-2.68.
Ibonisa ntoni isiphumo esithe nkqo?
Icima amanani angaphezulu kwendawo yakho ekhethiweyo ngaphandle kokujikelezisa nantoni na. 2. 673 ecutwa kumaziko amabini eshumi elinesiqingatha yi 2. 67, nokuba ukujikelezisa okufutshane kunika 2. 67 apha kwaye 2. 678 kuya kucutwa kwi 2. 67 ngelixa kujikelezisa kwi 2. 68.
Ndiyijikelezisa njani ixabiso lenani elibalulekileyo endaweni yendawo zeshumi?
Tshintsha indlela evela kumaziko eshumi elinesihlanu ukuya kumasuntswana abalulekileyo. Umgangatho we 3 ngoko ugcina amasuntswana amathathu okuqala abalulekileyo, ngoko 0. 0045213 ubonakala 0. 00452.
Ingaba ukujikelezisa phezulu kusoloko kuyenza inani ikhulu?
Kuphela kumanani alungileyo. Ukujikelezisa phezulu kuthetha ukujikeleza phezulu kukungaphelelanga okulungileyo, ngoko -2.7 kujikeleziswe phezulu kwinani elipheleleyo li -2, eli likhulu, alincinci.
API — sebenzisa le calculator ukusuka kwikhowudi
Nceda le khadi lemali njengendawo esemva ye-JSON ekhululekileyo - akukho qhosha lifunekayo. Thumela amaxabiso endawo ezantsi njengeparameter yombuzo okanye i-JSON.
