Tshem tawm qhov tseem ceeb hauv Microsoft Excel

Ntau tus neeg siv Excel tsis pom qhov txawv ntawm cov ntsiab lus ntawm "hom xov tooj ntawm tes" thiab "hom ntaub ntawv". Qhov tseeb, cov no yog deb ntawm cov ntsiab lus zoo tib yam, tab sis, ntawm chav kawm, lawv nyob hauv kev sib cuag. Cia peb kawm seb cov hom ntaub ntawv yog dab tsi, pawg twg tau muab faib rau, thiab seb koj tuaj yeem ua haujlwm nrog lawv.

Cov ntawv qhia hom ntawv

Cov hom ntaub ntawv yog tus cwj pwm ntawm cov ntaub ntawv khaws tseg rau hauv daim ntawv. Raws li qhov xeeb ceem, qhov kev zov me nyuam txiav txim siab yuav ua li cas ua tus nqi.

Cov hom ntaub ntawv tau muab faib ua ob pawg loj: kev ruaj khov thiab qauv. Qhov txawv ntawm ob yog tias cov qauv qhia tus nqi hauv ib lub xovtooj ntawm, uas txawv ntawm qhov kev sib tham ntawm lwm cov hlwb hloov. Constants yog qhov tseem ceeb uas tsis hloov.

Hauv lem, constants raug faib ua tsib pawg:

  • Cov ntawv nyeem;
  • Cov ntaub ntawv zauv;
  • Hnub tim thiab sijhawm;
  • Cov ntaub ntawv sau;
  • Erroneous qhov tseem ceeb.

Nrhiav kom paub tias txhua yam ntawm cov ntaub ntawv no qhia tau ntau tshaj.

Sau ntawv qhov tseem ceeb

Cov ntawv nyeem muaj cov ntaub ntawv cim thiab tsis xam tias Excel yog cov khoom ntawm cov lej zauv. Cov ntaub ntawv no feem ntau yog rau tus neeg siv, tsis yog rau qhov kev zov me nyuam. Cov ntawv nyeem yog ib lub cim, nrog rau cov zauv, yog tias lawv raug muab kho kom zoo. Hauv DAX, cov ntaub ntawv no yog hais txog qhov tseem ceeb ntawm txoj hlua. Cov ntawv nyeem ntev tshaj plaws yog 268435456 cim hauv ib lub xovtooj.

Sau cov cim qhia, xaiv lub xovtooj ntawm cov ntawv nyeem lossis cov qauv ntawm qhov uas nws yuav tsum muab, thiab ntaus cov ntawv los ntawm cov ntawv. Yog hais tias qhov ntev ntawm cov ntawv qhia tawm dhau qhov pom ntawm thaj chaw ntawm lub xov tooj, ces nws yog ib qho tseem ceeb tshaj rau cov uas nyob ib sab, tab sis nws yog lub cev khaws cia rau hauv qhov chaw ntawm tes.

Cov ntaub ntawv zauv

Rau kev tso nyiaj ncaj qha siv cov lus qhia numeric. Nws yog nrog lawv hais tias Excel ua rau ntau yam kev ua zauv (ntxiv, rho tawm, leb, faib, ntu tawm paus, thiab lwm yam). Hom ntaub ntawv no yog npaj rau kev sau cov zauv, tab sis nws kuj muaj cov cim pab cuam (%, $, thiab lwm yam). Nyob rau hauv kev sib raug zoo rau nws koj siv tau ntau hom kev tawm tswv yim:

  • Lus hauv no teb Ua tiag;
  • Tus nqi paj;
  • Nyiaj;
  • Nyiaj txiag;
  • Fractional;
  • Exponential.

Tsis tas li no, Excel muaj peev xwm faib cov zauv los ua cov lej, thiab txiav txim siab seb muaj pes tsawg tus zauv tom qab cov zauv ntawm cov zauv (hauv feem zauv).

Numeric cov ntaub ntawv yog sau tib yam li cov ntawv nyeem uas peb tham txog saum toj no.

Hnub tim thiab sijhawm

Lwm hom ntaub ntawv yog lub sijhawm thiab hnub hom. Qhov no yog qhov tseeb thaum cov ntaub ntawv hom thiab cov qauv siv tib yam. Nws yog tsi ntsees los ntawm qhov tseeb tias nws muaj peev xwm raug siv los qhia rau ntawm ib daim ntawv thiab nqa cov lus teb nrog cov hnub tim thiab lub sijhawm. Nws yog qhov tseem ceeb tshaj yog tias thaum lub sij hawm xam cov ntaub ntawv no yuav siv sij hawm ib hnub twg. Thiab qhov kev txhawj xeeb no tsis tsuas yog hnub, tab sis kuj lub sijhawm. Piv txwv li, 12:30 yog qhov kev zov me nyuam ua li 0.52083 hnub, thiab tsuas yog muab tso tawm rau hauv ib lub xov tooj ntawm tes hauv ib daim ntawv paub tus neeg siv.

Muaj ntau ntau hom sij hawm formatting:

  • h: hli: ss;
  • h: hli;
  • h: hli: ss AM / PM;
  • h: hli AM / PM, lwm yam.

Qhov teeb meem yog tib yam li cov hnub tim:

  • DD.MM.YYYY;
  • DD.MMM
  • MMM.GG thiab lwm tus.

Tseem muaj cov hnub thiab lub sijhawm ua ke, piv txwv li, hnub hli: Hli: YYYY h: mm.

Koj kuj yuav tsum xav txog tias qhov kev zov me nyuam tsuas yog qhov tseem ceeb hnub pib txij thaum xyoo 01/01/1900.

Cov ntaub ntawv sau

Teb zoo! Lus hauv no teb Loj nthuav yog hom logical cov ntaub ntawv. Nws ua hauj lwm nrog tsuas yog ob qhov tseem ceeb: "TRUE" thiab "CEEV FAJ". Yog tias koj ua rau siab, nws txhais tau hais tias "qhov kev tshwm sim tau tuaj" thiab "qhov kev tshwm sim tsis tau tuaj." Kev ua haujlwm, ua cov txheej txheem ntawm cov hlwb uas muaj kev paub cov ntaub ntawv, ua qee cov lus teb.

Erroneous qhov tseem ceeb

Cov ntaub ntawv cais yog qhov txawv txaag. Feem ntau, lawv tshwm sim thaum uas ua haujlwm tsis yog. Piv txwv li, kev ua haujlwm tsis xws yog kev faib tawm xoom los yog kev qhia txog kev ua haujlwm tsis muaj raws li nws cov lus sau tseg. Cov nqi ntawm qhov tsis tseem ceeb yog cov hauv qab no:

  • #VALUE! - siv hom kev sib cav tsis meej rau kev ua haujlwm;
  • # DEL / O! - faib los ntawm 0;
  • # TUS NAB NPAWB! - cov ntaub ntawv tsis muaj tseeb;
  • # N / A - tsis muaj nqi;
  • NPE? - lub npe yuam kev hauv hom mis;
  • # NULL! - tsis muaj qhov qhia txog qhov chaw nyob;
  • # LINK! - tshwm sim thaum lub hlwb keeb kwm uas lub mis los dhau los.

Cov qauv

Ib pawg loj ntawm ntau hom ntaub ntawv yog cov qauv. Tsis zoo li constants, lawv, feem ntau, tsis pom nyob rau hauv lub hlwb lawv tus kheej, tab sis tsuas yog tso tawm qhov tshwm sim, uas yuav txawv, nyob ntawm qhov kev hloov ntawm cov lus. Hauv particular, cov qauv no yog siv rau cov lej ntau yam. Tus qauv hauv nws tus kheej tuaj yeem pom nyob hauv tus qauv mis, qhov tseem ceeb ntawm lub cell uas nws muaj.

Ib qho yuav tsum tau ua ntej rau qhov kev zov me nyuam kom pom cov lus hais tias yog formula yog qhov muaj qhov kos npe rau ntawm nws lub xub ntiag (=).

Cov qauv no muaj cov references rau lwm lub hlwb, tab sis qhov no tsis yog ib qho uas yuav tsum tau ua.

Separate qauv yog cov haujlwm. Cov no yog cov kev ua haujlwm peculiar uas muaj kev tsim cov lus sib cav thiab ua raws li lawv qhov kev siv algorithm. Cov haujlwm yuav muab nkag mus rau hauv lub xovtooj ntawm tes los ntawm qhov ua ntej "="lossis koj tuaj yeem siv ib lub khauj khaum tshwj xeeb rau lub hom phiaj no. Function Wizard, uas muaj tag nrho cov neeg teb xov tooj muaj nyob rau hauv qhov kev zov me nyuam, muab faib ua pawg.

Nrog kev pab los ntawm Muaj nuj nqi masters Koj tuaj yeem ua qhov kev hloov mus rau qhov sib cav ntawm ib tus neeg teb xov tooj. Cov ntaub ntawv lossis txuas mus rau lub hlwb uas cov ntaub ntawv no muaj nyob hauv nws cov teb. Tom qab nias lub khawm "OK" lub sijhawm ua haujlwm tau teev tseg.

Raws li koj tau pom, hauv Excel muaj ob hom ntsiab lus ntawm hom ntaub ntawv: qhov ruaj thiab qauv. Lawv, lem, tau faib ua ntau hom. Txhua hom ntaub ntawv muaj nws tus kheej lub zog, raws li qhov kev pab cuam txheej txheem lawv. Mastering lub peev xwm los cim tau thiab ua hauj lwm kom raug nrog ntau hom ntaub ntawv yog thawj txoj hauj lwm ntawm txhua tus neeg siv uas xav kawm seb yuav siv Excel li cas rau nws lub hom phiaj.
