Nzira yekuverenga nhamba ye hexadecimal system
Iyo hexadecimal number system, inonziwo nheyo-16 kana dzimwe nguva hex chete , ndiyo nhamba yenhamba inoshandisa 16 zviratidzo zvakasiyana-siyana kuti zvimirire kukosha kweivo. Izvo zviratidzo zviri 0-9 ne AF.
Nhamba yehuwandu yatinoshandisa muupenyu hwezuva nezuva inonzi decimal , kana se-base-10 system, uye inoshandisa zviratidzo gumi kubva ku3 kusvika ku 9 kuti isirire kukosha.
Ndepi uye Nei Hexadecimal Inoshandiswa?
Nzira dzakawanda dzisina kukanganisa uye mamwe maitiro anoshandiswa mukati memakombiyuta inomiririrwa mumutambo we hexadecimal. Semuenzaniso, nhamba dzisina kukodzera dzinonzi STOP nhamba , dzinoratidzwa paBlue Screen of Death , dzinogara dziine hexadecimal format.
Vagadziri vanoshandisa nhamba ye hexadecimal nokuti maitiro avo akafupika kudarika zvaaizove akaoneswa muwedhi, uye shoma shoma kupfuura mumabhanari, anoshandisa 0 ne1 chete.
Somuenzaniso, iyo hexadecimal mutengo F4240 inofanana ne1000 000 mu decimal uye 1111 0100 0010 0100 0000 mune bhanary.
Imwe nzvimbo iyo hexadecimal inoshandiswa yakafanana neye HTML mhando yekhodi yekuratidza imwe ruvara. Somuenzaniso, web designer angashandisa hex kukosha FF0000 kuti ajekese ruvara rutsvuku. Izvi zvakaputsika seFF, 00,00, iyo inotsanangura huwandu hwemavara matsvuku, ehutema, uye ebhuruu inofanira kushandiswa ( RRGGBB ); 255 tsvuku, 0 ruvara, uye 0 bhuruu mumuenzaniso uyu.
Ichokwadi kuti hexadecimal inokosha kusvika ku255 inogona kuratidzirwa muzvidimbu zviviri, uye HTML mhando dzemitemo inoshandisa zvitatu zvemajeri maviri, zvinoreva kuti kune mamiriyoni gumi nematanhatu (255 x 255 x 255) inogona kuoneka mavara anogona kuratidzwa mu hexadecimal format, kuponesa mijenya yezvakaenzana nekutaura kwavari mune imwe fomu yakafanana neyakare.
Hungu, bhinari iri nyore nyore mune dzimwe nzira asiwo zvakare nyore nyore kwatiri kuverenga hexadecimal values kune zvinyorwa zvinowanikwa.
Nzira yekuverenga muHexadecimal
Kuverenga mumutauro we hexadecimal uri nyore chero bedzi iwe uchiyeuka kuti kune vanhu 16 vanoita nheyo imwe neimwe yenhamba.
Pakuwedzerwa mafaira, isu tose tinoziva kuti tinoverenga sezvizvi:
0,1,2,3,4,5,6,7,8,9,10,11,12,13, kuwedzera 1 asati atanga nheyo yemakumi gumi nenhamba zvakare (kureva nhamba 10).
Mune hexadecimal format asi, tinoverenga seizvi, kusanganisira nhamba gumi nemasere:
0,1,2,3,4,5,6,7,8,9, A, B, C, D, E, F, 10,11,12,13 ... zvakare, kuwedzera 1 asati atanga 16 nhamba yakatarwa zvakare.
Heano mienzaniso mishomanana yeimwe hexadecimal inotyisa "shanduko" yaunogona kuwana inobatsira:
... 17, 18, 19, 1A, 1B ...
... 1E, 1F, 20, 21, 22 ...
... FD, FE, FF, 100, 101, 102 ...
Nzira yekugadzirisa nayo manyore Hex Values
Kuwedzera hex maitiro akareruka uye chaizvoizvo kunoitwa nenzira yakafanana zvikuru kuverenga nhamba mu decimal decimal.
Dambudziko rinowanzosangana nematambudziko sa 14 + 12 rinowanzoitwa pasina kunyora chinhu pasi. Vakawanda vedu tinogona kuita izvozvo mumisoro yedu - ndeye 26. Heino imwe nzira inobatsira yekuitarisa:
14 yakaputsika kusvika 10 uye 4 (10 + 4 = 14), nepo 12 iri nyore se 10 uye 2 (10 + 2 = 12). Kana yakawedzerwa pamwe chete, 10, 4, 10, uye 2, yakaenzana ne 26.
Apo nhamba nhatu dzinoshandiswa, sa 123, tinoziva kuti tinofanira kutarisa panzvimbo dzose nhatu kuti tinzwisise zvavari kureva.
Iko 3 inomira pachayo nokuti ndiyo nhamba yekupedzisira. Bvisa mbiri dzokutanga, uye 3 dziripo 3. Iko 2 inowanikwa ne10 nekuti ndiyo inowiri yechipiri munhamba, seyakaita nemuenzaniso wekutanga. Zvakare, bvisa 1 kubva kune ichi 123, uye iwe wakasara ne 23, iyo 20 + 3. Nhamba yechitatu kubva kurudyi (1) inotorwa nguva 10, kaviri (dzimwe nguva 100). Izvi zvinoreva 123 kutendeuka kuva 100 + 20 + 3, kana 123.
Heano dzimwe nzira mbiri dzekutarisa:
... ( N X 10 2 ) + ( N X 10 1 ) + ( N X 10 0 )
kana ...
... ( N X 10 X 10) + ( N X 10) + N
Ivhara imwe nhamba panzvimbo yakakodzera mumutsetse unobva kumusoro kuti uende ku: 100 ( 1 X 10 X 10) + 20 ( 2 X 10) + 3 , kana kuti 100 + 20 + 3, iyo 123.
Izvozvowo ndezvechokwadi kana nhamba iri muzviuru, sa 1 234. Iko 1 ichokwadi 1 X 10 X 10 X 10, iyo inouita munzvimbo yechiuru, 2 muzana zana, nezvimwe zvakadaro.
Hexadecimal inowanikwa nenzira chaiyo asi inoshandisa 16 panzvimbo ye10 nokuti inotsika-16 system panzvimbo yepasi-10:
... ( N X 16 3 ) + ( N X 16 2 ) + ( N X 16 1 ) + ( N X 16 0 )
Somuenzaniso, titi tine dambudziko 2F7 + C2C, uye tinoda kuziva kukosha kwemhinduro yemhinduro. Iwe unofanira kutanga uchinje hexadecimal madijita kusvika kuwedzerwa, uye wozongowedzera huwandu pamwe chete sezvaunoda nemimienzaniso miviri iri pamusoro.
Sezvatakatsanangurira kare, zero kuburikidza nepfumbamwe mune zvose mbiri uye hex ndiyo yakanyatsofanana, asi nhamba gumi kusvika ku15 dzinomiririrwa seyeA A kusvika pa F.
Nhamba yekutanga kusvika kurudyi yakakosha ye hex inokosha 2F7 inomira payo, sezvinonzi decimal decimal, ichibuda kuva 7. Nhamba inotevera kuruboshwe yayo inofanira kuwedzerwa ne16, kufanana nenhamba yechipiri inobva 123 (2) pamusoro apa inoda kuwedzerwa ne 10 (2 X 10) kuita nhamba 20. Pakupedzisira, nhamba yechitatu kubva kurudyi inoda kuwedzera ne16, kaviri (iyo 256), sehamba yepamusoro-nhamba inoda kuwedzerwa ne10, kaviri (kana kuti 100), kana ine mitatu nhamba.
Saka, kuputsa 2F7 mumatambudziko edu kunoita kuti 512 ( 2 X 16 X 16) + 240 ( F [15] X 16) + 7 , iyo inouya kusvika ku759. Sezvaunogona kuona, F ndeyechi15 nekuda kwemoyo hex kuenzanisa (ona Nzira yekuverenga sei muHexadecimal kumusoro) - ndiyo nhamba yekupedzisira inobva pane inokwanisa 16.
C2C inoshandurwa kusvika kumatanho akadai: 3,072 ( C [12] X 16 X 16) + 32 ( 2 X 16) + C [12] = 3 1168
Zvakare, C yakaenzana ne12 nokuti ndiyo yegumi yechipiri apo iwe uri kuverenga kubva kune zero.
Izvi zvinoreva 2F7 + C2C chaizvoizvo 759 + 3,116, inokwana 3,875.
Kunyange zvazvo zvichifadza kuziva kuti ungazviita sei, zviri nyore zvikuru kushanda ne hexadecimal values ne calculator kana converter.
Hex Converters & amp; Calculators
A converter hexadecimal inobatsira kana iwe uchida kushandura hex kusvika kuwedzerwa, kana kudarika kune hex, asi haunoda kuzviita iwe pachako. Somuenzaniso, kupinda mu hex inokosha 7FF mune imwe shanduko ichakurumidza kukuudza kuti iyo yakaenzana nedzimba yepamusoro ndiyo 2 024.
Pane dzakawanda zvekutengesa hex dzekutsvaga zviri nyore chaizvo kushandisa, BinaryHex Converter, SubnetOnline.com, uye RapidTables vari zvishoma chete. Aya masayiti ngaarege kushandura kwete hex chete kusvika kudenga (uye zvimwewo) asiwo shandura hex uye kubva kubhinary, octal, ASCII, nevamwe.
Hexadecimal calculators inogona kunge yakagadzikana seyakagadzirisa purogiramu yekugadzirisa, asi inoshandiswa nehexadecimal values. 7FF pamwe ne 7FF, somuenzaniso, ndeye FFE.
Math Warehouse's hex calculator inobatanidza kusanganisa nheyo dzefoni. Imwe muenzaniso ingadai iri kuwedzera hex uye bhanari kukosha pamwe chete, uye zvino kutarisisa chigumisiro chemafomu ekudarika. Inotsigirawo octal.
EasyCalculation.com isati iri nyore nyore kuverenga. Ichakubvisa, kugovana, kuwedzera, uye kuwedzera hupi hupi hwema hex hunopa iwe, uye pakarepo kuratidza mhinduro dzose papeji imwecheteyo. Iyo inoratidzawo zviyero zvepamusoro zvinotevera kune hex mhinduro.
More Information on Hexadecimal
Izwi hexadecimal inosanganisira hexa (zvinoreva 6) uye decimal (10). Bhinary ishe-2, octal inotenderera-8, uye decimal ndeye, zvechokwadi, nheyo-10.
Hexadecimal values dzimwe nguva yakanyorwa neichirevo che "0x" (0x2F7) kana nebhadhiyo (2F7 16 ), asi haishanduri kukosha. Mune miviri mienzaniso iyi, unogona kuchengeta kana kudonha chibvumirano kana kubhadhara uye mari yepamusoro inoramba iri 759.
