Ka whakarerekētia te tuhipoka pūtaiao
Ka tahuri i tētahi tau ki te tuhipoka pūtaiao.
Ka whakahōutia ngā hua i te wā e tātuhi ana.
Mo tēnei tātaitai
Scientific notation writes a number as a coefficient between 1 and 10 multiplied by a power of ten, and this scientific notation converter turns any value into that form along with E-notation, engineering notation, its order of magnitude, and the plain standard-form number. It also reads scientific input, so you can convert in either direction.
To build the coefficient, the decimal point is moved so a single non-zero digit sits in front of it; the number of places moved becomes the exponent. So 12,345 has its point shifted four places to give 1.2345 × 10⁴, and small numbers use a negative exponent — 0.00045 becomes 4.5 × 10⁻⁴. Engineering notation keeps the exponent to a multiple of three (matching kilo, mega and so on), rewriting 12,345 as 12.345 × 10³, and the order of magnitude is just that power of ten, 4 here.
Scientific notation is how very large and very small quantities are handled in physics, astronomy, chemistry and computing without writing long strings of zeros. Entering a value in E-notation such as 1.2e5 converts it straight back to the standard number 120000.
Ko nga pātai e pā ana
He pēhea te tuhituhi i tētahi tau i roto i te tuhipoka pūtaiao?
Ka neke te ira tekauira kia noho ai tētahi mati kore-kore i mua i a ia, kātahi ka whakarea e 10 ki te tau o ngā wāhi kua nekehia. 12.345 = 1.2345 × 10⁴.
He aha te E-whakaahua?
Ko te E-notation te āhua o te whakaaturanga o ngā tātaitai i te tuhipoka pūtaiao: 1.2345 × 10⁴ e whakaaturia ana hei 1.2345e+4, i reira ko te tau i muri i te e te hiko o te tekau.
He aha te tuhipoka pūkaha?
He rite tonu ki te tuhipoka pūtaiao engari ka pupuritia te taupū ki te taumaha o te toru, nā reira ka whakarārangitia ki ngā tohu whakahau. Ka tuhituhitia te 12,345 hei 12.345 × 10³.
He aha te raupapa o te nui o tētahi tau?
Ko te hiko o te tekau i roto i tōna tuhipoka pūtaiao — te taupū. Mō te 12,345 ko te raupapa o te nui ko te 4.
Ka taea e au te tahuri i te E-notation ki tētahi tau pūnoa?
Hei. Type i tētahi uara pēnei i te 1.2e5 ā, ka whakawhānuitia e te kaiwhakarere ki te āhua paerewa 120.
He pēhea te tuhituhi i ngā tau iti rawa i roto i te tuhipoka pūtaiao?
Ka whakamahia e rātau tētahi taupū tōraro. Ka noho te 0.00045 hei 4.5 × 10−4, e neke ana i te pito e whā ngā wāhi ki te taha matau.
API — whakamahi tēnei tātaitai mai i te waehere
E kī ana tēnei tātaitai hei wāhi mutunga kore JSON - kāore he kī e hiahiatia ana. Ka tukuna ngā uara āpure i raro nei hei tohutoro pātai, JSON rānei. Anything you omit uses the same default this page is pre-filled with; an unknown parameter is a 400, never a silent zero. Ka pānui te papatono API katoa →
