Malunga nale Calculator
you want to round a number to a significant number of decimal places, you can use the standard nearest-value rounding. The standard nearest-value 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
Imibuzo ebuza rhoqo
Ujikeleziso lweendawo zeshumi lusebenza njani?
Bona umlinganiselo odlulayo kwinqanaba lokucima: 5 okanye ngaphezulu kokugquma phezulu, ngaphantsi kwe5 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.
