Momwe mungawerengere mu dongosolo la nambala ya hexadecimal
Nhamba ya nambala ya hexadecimal, yomwe imatchedwanso 16 kapena nthawi zina hex , ndiyo nambala yomwe imagwiritsa ntchito zizindikiro 16 zosiyana kuti ziyimirire mtengo wapadera. Zizindikiro zimenezo ndi 0-9 ndi AF.
Chiwerengero cha chiwerengero chomwe timagwiritsira ntchito tsiku ndi tsiku chimatchedwa decimal , kapena chigawo cha 10, ndipo chimagwiritsa ntchito zizindikiro 10 kuchokera ku 0 mpaka 9 kuti ziyimire mtengo.
Kodi ndi chifukwa chiyani hexadecimal ikugwiritsidwa ntchito?
Ma code ambiri olakwika ndi zida zina zomwe zimagwiritsidwa ntchito mkati mwa kompyuta zikuyimira mtundu wa hexadecimal. Mwachitsanzo, malemba olakwika omwe amatchedwa STOP , omwe amawonetseratu pa Blue Screen of Death , nthawi zonse amakhala omangamanga.
Olemba mapulogalamu amagwiritsa ntchito chiwerengero cha hexadecimal chifukwa zikhalidwe zawo ndizofupikitsa kuposa momwe zikanasinthidwira mu decimal, ndipo ndizofupikitsa kuposa momwe zimakhalira, zomwe zimagwiritsa ntchito 0 ndi 1 okha.
Mwachitsanzo, mtengo wa hexadecimal F4240 uli wofanana ndi 1,000,000 mu decimal ndi 1111 0100 0010 0100 0000 mu binary.
Malo ena a hexadecimal amagwiritsidwa ntchito ndi HTML code code kufotokoza mtundu winawake. Mwachitsanzo, wolemba webusaiti angagwiritse ntchito mtengo wa hex FF0000 kuti afotokoze mtundu wofiira. Izi zasweka monga FF, 00,00, yomwe imatanthauzira kuchuluka kwa mitundu yofiira, yobiriwira, ndi ya buluu yomwe iyenera kugwiritsidwa ntchito ( RRGGBB ); 255 wofiira, 0 wobiriwira, ndi 0 buluu mu chitsanzo ichi.
Mfundo yakuti hexadecimal imayambira mpaka 255 ikhoza kufotokozedwa mu ziwerengero ziwiri, ndipo zizindikiro za mtundu wa HTML zimagwiritsa ntchito magulu awiri a ziwerengero ziwiri, zikutanthawuza kuti pali zoposa 16 miliyoni (255 x 255 x 255) zovuta zomwe zingathe kufotokozedwa mu maonekedwe a hexadecimal, kupulumutsa malo ambiri poyerekeza ndi maonekedwe ena monga decimal.
Inde, binary ndi yophweka m'njira zina koma zimakhalanso zosavuta kuti tiwerenge maulendo a hexadecimal kusiyana ndi makhalidwe abwino.
Momwe mungawerenge mu hexadecimal
Kuwerengera mu chigawo cha hexadecimal ndi kosavuta mutakumbukira kuti pali zilembo 16 zomwe zimapanga manambala aliwonse.
Mu chikhalidwe cha decimal, tonse timadziwa kuti timawerengera monga izi:
0,1,2,3,4,5,6,7,8,9,11,12,13, kuwonjezera 1 asanayambe chiwerengero cha nambala khumi (kachiwiri nambala 10).
Mu chikhalidwe cha hexadecimal komabe, timawerengera monga izi, kuphatikizapo nambala 16:
0,1,2,3,4,5,6,7,8,9, A, B, C, D, E, F, 10,11,12,13 ... kachiwiri, kuwonjezera 1 asanayambe Nambala 16 yayikidwa kachiwiri.
Nazi zitsanzo zingapo za "kusintha" kosavuta kwa hexadecimal komwe mungapeze kothandiza:
... 17, 18, 19, 1A, 1B ...
... 1E, 1F, 20, 21, 22 ...
... FD, FE, FF, 100, 101, 102 ...
Mmene Mungasinthire Momasulira Makhalidwe Okhazikika
Kuwonjezera malingaliro a hex ndi osavuta ndipo kwenikweni kumachitidwa mwanjira yofananamo kuwerengera manambala mu dongosolo la decimal.
Matenda omwe amatha nthawi zonse monga 14+ 12 akhoza kuchitika popanda kulemba chilichonse. Ambiri a ife tingachite izi mitu yathu - ndi 26. Pano pali njira imodzi yothandiza kuyang'ana:
14 imasweka mpaka 10 ndi 4 (10 + 4 = 14), pamene 12 ndi yosavuta monga 10 ndi 2 (10 + 2 = 12). Powonjezedwa palimodzi, 10, 4, 10, ndi 2, zikufanana ndi 26.
Pamene manambala atatu akuyambitsidwa, monga 123, tikudziwa kuti tiyenera kuyang'ana malo atatu kuti timvetse tanthauzo lake.
A 3 amaima paokha chifukwa ndi nambala yomaliza. Chotsani awiri oyambirira, ndipo 3 adakali 3. A 2 akuchulukitsidwa ndi 10 chifukwa ndi chiwerengero chachiwiri mu chiwerengero, monga ndi chitsanzo choyamba. Apanso, chotsani 1 kuchokera 123, ndipo mwatsalira ndi 23, omwe ali 20 + 3. Nambala yachitatu kuchokera kumanja (1) imakhala nthawi 10, kawiri (nthawi 100). Izi zikutanthauza kuti 123 akutembenukira ku 100 + 20 + 3, kapena 123.
Nayi njira zina ziwiri zomwe mungaziwonere:
( N X 10 2 ) + ( N X 10 1 ) + ( N X 10 0 )
kapena ...
... ( N X 10 X 10) + ( N X 10) + N
Lembani chiwerengero chilichonse pa malo oyenera kuchokera pamwambapa kuti mukhale: 100 ( 1 X 10 X 10) + 20 ( 2 X 10) + 3 , kapena 100 + 20 + 3, omwe ali 123.
Zomwezo ndizoona ngati chiwerengero chiri mu zikwi, ngati 1,234. The 1 ilidi 1 X 10 X 10 X 10, yomwe imapanga malo chikwi, 2 mu hundredths, ndi zina zotero.
Hexadecimal yachita chimodzimodzi koma imagwiritsira ntchito 16 mmalo mwa 10 chifukwa ndizoyikidwa pansi pa 16 m'malo mwazomwe-10:
( N X 16 3 ) + ( N X 16 2 ) + ( N X 16 1 ) + ( N X 16 0 )
Mwachitsanzo, titi tili ndi vuto 2F7 + C2C, ndipo tikufuna kudziwa yankho la decimal la yankho. Muyenera kuti mutembenuzire chiwerengero cha hexadecimal kukhala chiwerengero, ndiyeno kungowonjezerani nambala pamodzi monga momwe mungakhalire ndi zitsanzo ziwiri pamwambapa.
Monga momwe tafotokozera kale, zero kupyolera zisanu ndi zinayi m'ma decimal onse ndi hex ndizofanana, pamene nambala 10 mpaka 15 zikuyimiridwa ngati makalata A mpaka F.
Nambala yoyamba kupita kumanja yakutali ya mtengo wa hex 2F7 imadziimira yokha, monga mu decimal, ikufika pokhala 7. Nambala yotsatira kumanzere kwake iyenera kuwonjezeka ndi 16, mofanana ndi chiwerengero chachiwiri kuchokera ku 123 (2) pamwambapa amafunika kuchulukitsidwa ndi 10 (2 X 10) kuti apange chiwerengero 20. Pomalizira, nambala yachitatu yomwe ikufunikira kuwonjezeka ndi 16, kawiri (yomwe ndi 256), ngati nambala yozikidwiratu amafunika kuchulukitsidwa ndi 10, kawiri (kapena 100), pamene ali ndi manambala atatu.
Choncho, kuthetsa 2F7 mu vuto lathu kumapangitsa 512 ( 2 X 16 X 16) + 240 ( F [15] X 16) + 7 , yomwe imafika ku 759. Monga mukuonera, F ndi 15 chifukwa cha malo ake Mndandanda wa hex (onani momwe mungawerenge mu hexadecimal pamwamba) - ndi nambala yotsiriza yomwe simungathe.
C2C imasinthidwa kukhala ngati: 3,072 ( C [12] X 16 X 16) + 32 ( 2 X 16) + C [12] = 3,116
Kachiwiri, C ndi ofanana ndi 12 chifukwa ndi mtengo wa 12 pamene mukuwerengera kuchokera ku zero.
Izi zikutanthauza 2F7 + C2C kwenikweni 759 + 3,116, yomwe ili yofanana ndi 3,875.
Ngakhale kuti ndi bwino kudziwa momwe mungagwiritsire ntchito izi, ndizosavuta kugwira ntchito ndi zida za hexadecimal ndi calculator kapena converter.
Hex Converters & amp; Owerenga
Wotembenuza wa hexadecimal ndiwothandiza ngati mukufuna kutanthauzira hex ku decimal, kapena decimal kukhala hex, koma simukufuna kuzichita mwadongosolo. Mwachitsanzo, kulowa mu hex mtengo 7FF mu converter adzakuuzani mwamsanga kuti ofanana decimal mtengo ndi 2,047.
Pali ambiri otembenuza ma hex omwe amagwiritsa ntchito, BinaryHex Converter, SubnetOnline.com, ndi RapidTables kukhala ochepa chabe. Masamba awa musalole kutembenuza mphekesera mpaka decimal (komanso mosiyana) koma mutembenuzirenso hex ndi kuchokera ku binary, octal, ASCII, ndi ena.
Ma calculates a hexadecimal angakhale othandiza ngati a decimal calculator, koma kuti agwiritsidwe ntchito ndi ma hexadecimal values. 7FF komanso 7FF, mwachitsanzo, ndi FFE.
Hex calculator yolumikiza masitimu imaphatikizapo kuphatikiza machitidwe a nambala. Chitsanzo chimodzi chikhoza kuwonjezera phindu limodzi ndi phindu limodzi, ndikuyang'ana zotsatirapo ndi maonekedwe a decimal. Amathandizanso octal.
EasyCalculation.com ndi wowerengera wosavuta kugwiritsa ntchito. Icho chidzachotsa, kugawa, kuwonjezera, ndi kuchulukitsa maulaliki awiri omwe mumapereka, ndipo nthawi yomweyo muzisonyeza mayankho onse pa tsamba lomwelo. Amasonyezanso ziwerengero zam'madera pafupi ndi mayankho a hex.
Zambiri Zokhudza Hexadecimal
Mawu akuti hexadecimal ndi kuphatikiza hexa (kutanthauza 6) ndi decimal (10). Binary ndi maziko a 2, octal ndi oyambira-8, ndipo decimal ndi, ndithudi, maziko-10.
Malamulo a hexadecimal nthawi zina amalembedwa ndi chikhomo "0x" (0x2F7) kapena ndi subscript (2F7 16 ), koma sasintha mtengo. Mu zitsanzo zonsezi, mukhoza kusunga kapena kuchotsa chiwerengerocho kapena subscriptions ndipo mtengo wamtengo wapatali ukhoza kukhala 759.
