Pehea e helu ai i ka pūnaewele helu hexadecimal
ʻO ka pūnaewele helu hexadecimal, i kapaʻia he base-16 aiʻole he mau manawa hex wale nō, he pūnaewele pūnaewele e hoʻohana ana i 16 mau hiʻohiʻona likeʻole e hōʻike i kahi waiwai. ʻO kēlā mau hōʻailonaʻo 0-9 a me AF.
ʻO ka pūnaehana helu mākou e hoʻohana ai i kēia ao i kapaʻia he decimal , a 10 base-10 pūnaewele, a hoʻohana i nā hiʻohiʻona 10 mai ka 0 a 9 e hōʻike i kahi waiwai.
Kahi a no ke aha i hoʻohanaʻia ai hexadecimal?
ʻO ka hapa nui o nā hewa a me nā kumuhana'ē aʻe i hoʻohanaʻia i loko o kahi kamepiula e paniʻia ana i ka hōʻano hexadecimal. Eia kekahi laʻana,ʻo nā mea hewa i kapaʻia he mau STOP , e hōʻike ana ma kahi Blue Screen of Death , ma keʻano hexadecimal.
Hoʻomaopopo nā polokalamu polokalamu Polokalamu i nā helu hexadecimalō no ka mea pōkole ko lākou mau waiwai ma mua o ka hōʻikeʻana i ka decimal, aʻoi aku ka pōkole ma mua o keʻano binary, kahi hoʻohana wale nō 0 a me 1.
Eia kekahi laʻana,ʻo ka helu hexadecimal F4240 he like ia me 1,000,000 ma ka decimal a 1111 0100 0010 0100 0000 ma keʻano binary.
ʻO kekahi wahi hexadecimal e hoʻohanaʻia nei heʻano laulā HTML no ka hōʻikeʻana i kahiʻano. Eia kekahi laʻana, e hoʻohana ka mea hoʻolālā pūnaewele i ka helu hex FF0000 e ho'ākāka i kaʻulaʻula. Ua hakiʻia kēia ma FF, 00,00, e wehewehe ana i ka nui o nā kalaʻulaʻulaʻula,'ōmaʻomaʻo, a me kaʻulaʻula e pono e hoʻohanaʻia ( RRGGBB ); 255ʻulaʻula, 0'omaʻomaʻo, a me ka uliuli 0 kēia hiʻohiʻona.
ʻO kaʻoiaʻiʻo o ka helu hexadecimal a hiki i 255 hiki ke hōʻikeʻia i nā heluʻelua, aʻo nā wae kala laula o HTML ke hoʻohana iʻekolu papa o nā heluʻelua,ʻo ia hoʻi, aia ma kahi o 16 miliona (255 x 255 x 255) hiki i nā kala e hiki ke ho'ākākaʻia ma ka hōʻano hexadecimal, me kaʻikeʻole i nā mea he nui me ka hōʻikeʻana iā lākou ma kekahiʻano'ē aʻe e like me ka decimal.
ʻAe,ʻoi aku ka maʻalahi o ka binary ma kekahi mauʻano akā he mea maʻalahi loa ia no ka heluheluʻana i nā helu hexadecimal ma mua o nā mea maʻamau.
Pehea e helu ai i Hexadecimal
Hiki ke maʻalahi i ka hōʻano hexadecimal ma muli o kou hoʻomanaʻoʻana he 16 mau hua'ōlelo e hakuʻia ana kēlā me kēia helu helu.
Ma ka palapala decimal, ua maopopo iā mākou ke helu nei mākou penei:
0.1,2,3,4,5,6,7,8,9,10,11,12,13, ... e hoʻonui ana i 1 ma mua o ka hoʻomakaʻana o ka hoʻonohonohoʻana o 10 mau helu (ʻo ia hoʻi ka helu 10).
I loko o ka hōʻailona hexadecimal, akā, ke helu nei mākou i kēia, me nā helu he 16:
0.1,2,3,4,5,6,7,8,9, A, B, C, D, E, F, 10,11,12,13 ... hou, e houluulu i 1 mamua o ka hoomaka ana o ka Ua helu houʻia ka helu hou.
Eia kekahi mau hiʻohiʻi o kekahi mau "transitions" hexadecimalʻoʻoleʻa e hiki ai iāʻoe ke kōkua:
..., 17, 18, 19, 1A, 1B ...
... 1E, 1F, 20, 21, 22 ...
... FD, FE, FF, 100, 101, 102 ...
Pehea e hoʻololi i nā Uila Hex
He mea maʻalahi ka hoʻonuiʻana i nā kaʻina hex a ua hana maoli ia ma kahiʻano likeʻole e helu ai i nā helu ma ka pūnaha decima.
Hiki ke hana maʻamau i nā pilikia maʻamau e like me 14 + 12 me ka kākauʻoleʻana i kekahi mea. E hiki i ka hapanui o mākou ke hana i kēlā mea ma ko mākou mau poʻo - eia 26. Eia kekahi ala kōkua e nānā ai iā ia:
14 ua haki i lalo i 10 a me 4 (10 + 4 = 14), aʻo 12 ke hoʻololiʻia he 10 a me 2 (10 + 2 = 12). I ka manawa i hui pūʻia ai, 10, 4, 10, a me 2, like 26.
Ke hōʻea mai nā huaheluʻekolu, e like me 123,ʻike mākou e pono iā mākou ke nānā i nā wahiʻekolu a maopopo i keʻano o kā lākou manaʻo.
Ke kū nei ke 3 i kona iho no ka meaʻo ia ka helu hope loa. E hoʻokaʻawale i nā mea muaʻelua, aʻo 3 ka 3. Ua hoʻonuiʻia ka 2 i 10 no ka meaʻo ia ka helu lua o ka helu, e like me keʻano hoʻohālike. Eia hou, e lawe i ka 1 mai kēia 123, a koe i 23, 20 + 3. ʻO ka heluʻekolu mai ka'ākau (1) e laweʻia i 10 mau manawa,ʻelua (manawa 100). Penei ka 123 i lilo i 100 + 20 + 3, aiʻole 123.
Eia nāʻano'ē aʻe e nānā ai iā ia:
... ( N X 10 2 ) + ( N X 10 1 ) + ( N X 10 0 )
a ...
... ( N X 10 X 10) + ( N X 10) + N
Hoʻohui i kēlā me kēia helu i ka wahi kūpono ma ka hoʻopihapiha mai luna ae i ka 123 i loko o: 100 ( 1 X 10 X 10) + 20 ( 2 X 10) + 3 , aiʻole 100 + 20 + 3, nona 123.
Pēlāʻoiaʻiʻo ināʻo ka helu i loko o nā mano, e like me 1,234. ʻO ka 1 he 1 X 10 X 10 X 10, aʻo ia ka mea ma kahi o kahi mano, 2 ma nā haneri, a pēlā aku.
Hanaʻiaʻo Hexadecimal ma keʻano hoʻokahi akā ua hoʻohana i 16 ma kahi o 10 no ka mea, he base-16 pūnaewele ma kahi o ka base-10:
... ( N X 16 3 ) + ( N X 16 2 ) + ( N X 16 1 ) + ( N X 16 0 )
Eia kekahi laʻana, e'ōlelo ana mākou i ka pilikia 2F7 + C2C, a makemake mākou eʻike i ka helu decimal o ka pane. Ponoʻoe e hoʻololi mua i nā hua'ōlelo hexadecimal i decimal, a laila e hoʻohui i nā helu i like me kāu e hana nei me nā hiʻohiʻonaʻelua ma luna nei.
E like me kā mākou i ho'ākāka mua nei,ʻeleʻele i loko oʻeiwa i loko o nā decimal a me nā hex a like nō ia, aʻo nā helu 10 a hiki i 15 ke paniʻia e like me nā leka A a hiki i F.
ʻO ka helu mua i ka'ākau pololei o ka hex value 2F7 e kū ana i kona iho, e like me ka'ōkuhi decimal, e puka mai ana he 7. E hoʻonuiʻia ka helu ma hope i ka 16, e like me ka heluʻelua mai ka 123 (ka 2) ma luna pono e hoʻonuiʻia e 10 (2 X 10) e hana i ka helu 20. Ma hope, pono e hoʻonuiʻia ka heluʻekolu mai ka'ākau i 16, pālua (ʻo ia hoʻi 256), e like me ka helu kaulike pono e hoʻonuiʻia i ka 10,ʻelua (aiʻole 100), ināʻekolu mau helu.
No laila,ʻo ka uhakiʻana i ka 2F7 i ko mākou pilikia ka 512 ( 2 X 16 X 16) + 240 ( F [15] X 16) + 7 , hiki mai i 759. E like me kouʻikeʻana,ʻo F he 15 no kona kūlana ma ka Hex laina (e nānā i pehea e helu ai i ka Hexadecimal ma luna aʻe) -ʻo ia ka helu hope loa mai ka lā 16.
Hoʻololiʻia ka C2C i decimal e like me kēia: 3,072 ( C [12] X 16 X 16) + 32 ( 2 X 16) + C [12] = 3,116
Eia hou, ua likeʻo C me 12 no ka mea,ʻo ia ka 12 o ka waiwai ke heluʻoe mai ka zero.
ʻO kēia keʻanoʻo 2F7 + C2C he 759 + 3,116, he like ia me 3,875.
ʻOiai maikaʻi ia eʻike i keʻano o kēia hana lima, hiki ke maʻalahi ka hanaʻana me nā helu hexadecimal me kahi calculator a hoʻololi paha.

Nāʻike hou aʻe no Hexadecimal
ʻO ka hua'ōlelo hexadecimal he hui pūʻia o hexa (mean 6) a me decimal (10). ʻO ka binary-base-2, octal-base-8, aʻo ka decimal he,ʻoiaʻiʻo, base-10.
