Yuav ua li cas suav nyob rau hauv lub hexadecimal tooj system
Hexadecimal naj npawb system, hu ua base-16 los yog tej zaum tsuas yog hex , yog ib tug xov tooj uas siv 16 cim cim los sawv cev rau ib qho nqi. Cov cim no yog 0-9 thiab AF.
Cov naj npawb uas peb siv hauv lub neej txhua hnub yog hu ua decimal , los yog lub hauv paus pib ntawm 10, thiab siv 10 cim ntawm 0 mus txog 9 los sawv cev rau tus nqi.
Qhov twg thiab vim li cas siv Hexadecimal?
Feem ntau cov lis dej num yuam kev thiab lwm yam khoom siv hauv lub koos pis tawj yog sawv cev hauv hom ntawv hexadecimal. Piv txwv, yuam kev lis dej num hu ua STOP codes , uas tso rau ntawm Blue Screen of Death , yog ib txwm nyob hauv hom ntawv hexadecimal.
Cov programmers siv cov hexadecimal tooj vim tias lawv qhov tseem ceeb yog luv dua lawv yuav tsum yog tso tawm hauv decimal, thiab luv dua li hauv binary, uas tsuas siv 0 thiab 1.
Piv txwv, tus nqi hexadecimal F4240 yog sib npaug rau 1,000,000 zauv thiab 1111 0100 0010 0100 0000 hauv binary.
Lwm qhov chaw hexadecimal yog siv los ua ib qho HTML xim xim los nthuav qhia cov xim tshwj xeeb. Piv txwv, tus kws tsim tawm lub website yuav siv tus nqi hex FF0000 los txheeb xyuas cov xim liab. Qhov no tau tawg cia li FF, 00,00, uas txhais cov xim liab, ntsuab, thiab xiav xim uas yuav tsum tau siv ( RRGGBB ); 255 liab, 0 ntsuab, thiab 0 xiav ntawm qhov piv txwv.
Qhov tseeb tias qhov tseem ceeb txog 255 yuav tsum hais ua ob tug lej, thiab HTML xim xim siv 3 pawg ntawm ob tug lej, nws txhais tau hais tias muaj tshaj 16 lab (255 x 255 x 255) cov xim uas tuaj yeem hais hauv hom ntawv hexadecimal, txuag ntau ntawm chaw seem tiv thaiv lawv nyob rau hauv lwm hom zoo li decimal.
Yog, binary yog yooj yim dua hauv ib txoj hauv kev tab sis nws tseem yooj yim dua rau peb nyeem hexadecimal qhov tseem ceeb tshaj binary qhov tseem ceeb.
Yuav ua li cas suav hauv Hexadecimal
Suav nyob hauv hom ntawv hexadecimal yog ib qho yooj yim tsuav yog tias koj nco ntsoov tias muaj 16 cim uas tsim txhua tus lej.
Hauv decimal format, peb txhua tus paub tias peb suav zoo li no:
0,1,2,3,4,5,6,7,8,9,10,11,12,13, ... ntxiv rau 1 ua ntej pib qhov txheej ntawm 10 tus lej dua (piv txwv li tus lej 10).
Nyob rau ntawm hom ntawv hexadecimal tiam sis, peb suav zoo li qhov no, nrog rau tag nrho cov naj npawb 16:
0,1,2,3,4,5,6,7,8,9, A, B, C, D, E, F, 10,11,12,13 ... dua, ntxiv ib 1 ua ntej pib 16 tus xov tooj teem dua.
Ntawm no yog ob peb qhov piv txwv ntawm qee tus cim tias nws hloov "zaus" uas koj tuaj yeem pab tau:
... 17, 18, 19, 1A, 1B ...
... 1E, 1F, 20, 21, 22 ...
... FD, FE, FF, 100, 101, 102 ...
Yuav ua li cas Manually hloov Hex Values
Ntxiv cov hex qhov tseem ceeb yog yooj yim heev thiab tau ua tiav ib txoj hauv kev zoo li suav cov zauv nyob hauv cov zauv.
Ib qho teeb meem ntawm kev ua lej zoo li 14 + 12 tuaj yeem ua tau yog tias tsis sau dab tsi cia. Feem ntau ntawm peb tuaj yeem ua li ntawd hauv peb lub taub hau - nws yog 26. Ntawm no yog ib txoj kev uas yuav pab tau nws:
14 poob mus rau hauv 10 thiab 4 (10 + 4 = 14), thaum 12 yog simplified li 10 thiab 2 (10 + 2 = 12). Thaum ntxiv ua ke, 10, 4, 10, thiab 2, sib npaug 26.
Thaum peb muaj peb tug lej ua ke, zoo li 123, peb paub tias peb yuav tsum saib tag nrho peb qhov chaw kom nkag siab lawv txhais li cas.
Lub 3 sawv ntawm nws tus kheej vim nws yog tus lej kawg. Tshem tawm thawj ob, thiab 3 tseem yog 3. Qhov 2 yog multiplied los ntawm 10 vim nws yog tus naj npawb ob hauv tus naj npawb, ib yam nkaus li nrog tus qauv thawj. Ntxiv dua thiab, tshem tawm cov 1 ntawm 123, thiab koj nyob nraum nrog 23, uas yog 20 + 3. Qhov thib peb tus naj npawb ntawm txoj cai (tus 1) yog lub sij hawm 10, ob zaug (zaug 100 zaus). Qhov no txhais tau tias 123 tig mus rau 100 + 20 + 3, los yog 123.
Ntawm no yog ob txoj kev los saib nws:
... ( N X 10 2 ) + ( N X 10 1 ) + ( N X 10 0 )
los sis ...
... ( N X 10 X 10) + ( N X 10) + N
Muab txhua lub zauv rau hauv qhov chaw nyob hauv qhov ua kom haum ntawm saum toj no los hloov 123 rau: 100 ( 1 X 10 X 10) + 20 ( 2 X 10) + 3 , los yog 100 + 20 + 3, uas yog 123.
Tib yam muaj tseeb yog hais tias tus xov tooj yog nyob rau hauv ntau txhiab, xws li 1,234. Lub 1 yog tiag 1 X 10 X 10 X 10, uas ua rau nws nyob rau hauv lub txhiab tus qhov chaw, 2 nyob rau hauv lub hundredths, thiab thiaj li nyob rau.
Hexadecimal yog ua raws nraim li tab sis siv 16 es tsis txhob 10 vim nws yog lub hauv paus-16 qhov system tsis yog lub hauv paus-10:
... ( N 3 16) + ( N X 16 2 ) + ( N X 16 1 ) + ( N X 16 0 )
Piv txwv, hais tias peb muaj qhov teeb meem 2F7 + C2C, thiab peb xav paub txog cov zauv ntawm cov lus teb. Koj yuav tsum tau hloov cov lej hexadecimal rau decimal, thiab tom qab ntawd ces ntxiv cov lej ua ke zoo li koj xav nrog ob qho ua piv txwv saum toj no.
Zoo li peb tau piav qhia, xoom dhau cuaj rau ob qho zauv thiab hex yog tib yam nkaus, thaum naj npawb 10 txog 15 yog sawv cev rau cov tsiaj ntawv A ntawm F.
Thawj tus naj npawb mus rau sab xis ntawm tus nqi hex 2F7 sawv ntawm nws tus kheej, zoo li nyob rau hauv cov zauv system, tabtom tawm los ua 7. Tus naj npawb txuas mus rau nws sab laug xav tau kev pab cuam los ntawm ntau dua 16, ntau npaum li ob tus naj npawb ntawm 123 (2) qhov yuav tsum tau ua kom khoo tau los ntawm 10 (2 X 10) los ua tus naj npawb 20. Thaum kawg, tus naj npawb ntawm peb txoj cai xav tau kom muab ntau dua los ntawm 16, ob zaug (uas yog 256), zoo li ib tug zauv zauv yuav tsum tau muab sib tw los ntawm 10, ob zaug (los yog 100), thaum nws muaj peb tug lej.
Yog li, txhawm rau 2F7 ntawm peb qhov teeb meem ua rau 512 ( 2 X 16 X 16) + 240 ( F [15] X 16) + 7 , uas tuaj mus rau 759. Raws li koj tau pom, F yog 15 vim nws txoj hauj lwm hauv Hex sib lawv liag (saib Yuav ua li cas suav rau Hexadecimal saum toj no) - nws yog qhov kawg ntawm tus xov tooj tsis tau 16.
C2C hloov dua siab tshiab rau decimal zoo li no: 3,072 ( C [12] X 16 X 16) + 32 ( 2 X 16) + C [12] = 3,116
Ntxiv dua thiab, C yog sib npaug rau 12 vim nws yog tus nqi 12 thaum koj suav ntawm xoom.
Qhov no txhais tau hais tias 2F7 + C2C yog 759 + 3,116, uas yog sib npaug li 3,875.
Thaum nws tseem zoo yuav tsum paub ua li cas ua manually, nws yog kiag li yooj yim rau kev ua hauj lwm nrog hexadecimal qhov tseem ceeb nrog lub laij lej los yog hloov khoom.
Hex Converters & amp; Tshuab xam zauv
Ib lub hexadecimal converter yog qhov tseem ceeb yog tias koj xav tau txhais hex rau decimal, los yog decimal rau hex, tab sis tsis xav ua nws manually. Piv txwv, nkag mus rau tus nqi ntawm 7x 7FF rau hauv ib lub converter yuav qhia rau koj tias qhov sib npaug ntawm tus zauv yog 2,047.
Muaj ntau ntau hauv online hex converters uas yog tiag tiag yooj yim mus siv, BinaryHex Converter, SubnetOnline.com, thiab RapidTables yog ib txhia ntawm lawv. Cov chaw no cia koj hloov tsis tsuas hex rau decimal (thiab vice versa) tab sis kuj hloov hex mus thiab los ntawm binary, octal, ASCII, thiab lwm tus.
Hexadecimal lub laij lej ntsuas tau ua ke raws li kev siv zauv los ua tus zauv, tab sis siv rau cov lus hexadecimal. 7FF ntxiv rau 7FF, piv txwv li, yog FFE.
Math Warehouse tus hex tshuab xam zauv txhawb kev sib koom tes. Ib qho piv txwv yuav muab ntxiv rau tus hex thiab binary nqi ua ke, thiab tom qab ntawd saib qhov tshwm sim hauv decimal. Nws kuj txhawb kev octal.
EasyCalculation.com yog lub tshuab xam xaj yooj yim siv. Nws yuav rho tawm, sib faib, ntxiv, thiab muab tus nqi qis tshaj ob qho lus uas koj muab rau nws, thiab saib txhua lo lus teb rau tib nplooj ntawv. Nws kuj qhia tau hais tias cov zauv muaj sib npaug ntawm cov lus teb rau cov lus nug.
Xav paub ntxiv txog Hexadecimal
Lo lus hexadecimal yog ib qho ua ke ntawm hexa (ntsiab 6) thiab decimal (10). Binary yog puag-2, octal yog puag-8, thiab decimal yog, tau kawg, pib-10.
Hexadecimal qhov tseem ceeb yog qee zaum sau nrog "prefix" 0x (0x2F7) los yog nrog ib tus ntawv cim (2F7 16 ), tab sis nws tsis hloov tus nqi. Hauv ob qho ntawm cov qauv no, koj yuav khaws los yog tso tseg cov lus prefix lossis subscript thiab cov zauv muaj nqis yuav nyob txuas ntxiv 759.
