Te tātaitai whāiti
Ka whakawhāititia tētahi tau ki tētahi tau o ngā tau ā-ira, ki runga, ki raro rānei.
Ka whakahōutia ngā hua i te wā e tātuhi ana.
Mo tēnei tātaitai
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 always-up (ceiling) mode counts the extra digits from the first non-zero one instead, and a negative number of places rounds to the left of the point becomes 3500. The always-down (floor) mode counts the value is rounded to the digit just past the cut-off.Rou
Ko nga pātai e pā ana
He pēhea te mahi o te whakaroa ki ngā tauwāhi ira?
Tirohia te mati i muri i te whakawhāiti: 5 neke atu rānei i te porowhita ki runga, iti iho i te 5 porowhita ki raro. 3.14159 ki ngā wāhi e rua ko te 3.14.
He aha te mahi a te tau tōraro o ngā tau ira?
Ka whakarurua ki te taha mauī o te ira ira: −1 ki te tekau mā iwa tata, −2 ki te rau tata. Ko te 3457 ki ngā wāhi −2 ko te 3500.
He aha te rerekētanga i waenganui i te whakaroanga ki runga me te whakaroanga ki raro?
Ka neke te whakaroa ki runga (rohe) ki te uara nui ake i ngā wā katoa, ā, ka whakaroa ki raro (papa) ki te iti iho, i te wā e kōwhiria ana te tino tata ki te tata ake.
He aha te whakaaturanga o te hua whakawhāiti?
Ka whakaiti i ngā mati i waho o tōna tauwāhi i kōwhiria me te kore e whakaroa. 2.673 i whakaroa ki ngā tau ira e rua, ko te 2.67, ahakoa ka hoatu hoki te whakaroa tata ki te 2.67 i tēnei wāhi, ā, ka whakaroa te 2.67 ki te 2.67 i te wā e whakaroa ana ki te 2.68.
He pēhea te whakaroa i a au ki ngā mati hira i te wāhi ira?
Ka huri te tikanga mai i ngā wāhi ira ki ngā mati hira. Ka pupuri te tika o te 3 i ngā mati whai tikanga tuatahi e toru, nō reira ka noho te 0.0045213 hei 0.00452.
Ka nui ake te tau i ngā wā katoa te whakarurutanga?
Mō ngā tau tōrunga anake, ko te tikanga o te whakaroa ki runga ki te mutunga tōrunga, nō reira ko te −2.7 i whakaroa ki tētahi tau tōpū ko te −2, he nui ake, kāore i te iti iho.
