Ku saabsan Kalkaaliyahan
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.
Su'aalaha badanaa la isweydiiyo
Sidee ku wareegsan in meelaha tirada tirada ah shaqada?
Fiiri lambarka kaliya ka hor inta aan la goyn: 5 ama in ka badan wareegyada kor, ka yar 5 wareegyada hoos. 3.14159 laba meelood oo ah 3.14.
Maxaa ka dhigan yahay tirada xun ee meelaha tirada ah sameeyaan?
Waxay ku wareegsan tahay dhinaca bidix ee dhibcaha tirakoobka: -1 wareegsan toban ugu dhow, -2 ilaa boqol ugu dhow. 3457 ilaa -2 meelaha waa 3500.
Maxaa u dhexeeya kala duwanaanta u wareegsan iyo u wareegsan hoos?
Rounding up (saqafka) marwalba u dhaqdhaqaaqa qiimaha weyn iyo rounding hoos (saqafka) in ka yar, halka ugu dhow ee dooranaya mid ka mid ah oo ku dhow. For 2.673 laba meelood, ugu dhow iyo hoos u siiyaan 2.67 laakiin up siiyaa 2.68.
Maxaa ka dhigaya natiijada la gooyo muujinaya?
2.673 la gooyo ilaa laba meelood oo tirakoobka ah waa 2.67, in kastoo ku dhow wareegsan sidoo kale siiyaa 2.67 halkan iyo 2.678 la gooyo ilaa 2.67 inta ku wareegsan 2.68.
Sidee baan u wareegaa si ay u muujiyaan si ay u badalaan meelaha tirada tirada ah?
Isku beddel habka laga bilaabo meelaha tirakoobka in tirada muhiimka ah. A sax ah oo 3 markaas haysta saddexda lambarka muhiimka ah ee hore, sidaa darteed 0.0045213 noqdaa 0.00452.
Ma wareegsan ilaa iyo inta aad ka dhigi kartaa tirada ka weyn?
Marka la isku wareego waxaa loola jeedaa in la gaadho xad aan dhammaad lahayn, sidaa darteed −2.7 oo la isku wareego ilaa tirada buuxda waa −2, taas oo ka weyn, aan ka yar.
API — isticmaal xisaabinta ka code
Wici xisaabinta sida free JSON endpoint - key ma loo baahan yahay. Dib u soo dir qiimaha goobta hoos ku qoran sida parameters su'aal ama JSON. Wax kasta oo aad ka maqan tahay isticmaalaa default la mid ah ee boggani waa hore loo buuxiyey la; parameter aan la aqoon waa 400, marnaba ma aha zero maqan. Akhri dhammaan API xuquuqda →
