Maandishi kwa desimali

Badilisha maandishi kuwa uwakilishi wa desimali kwa urahisi

Chombo cha kubadilisha fedha

0 characters

Enter text to convert to decimal values. Choose between UTF-8 (supports all characters) and ASCII (only 128 characters). Options to add spaces between decimal values are available.

Kuhusu Maandishi hadi Ubadilishaji wa Desimali

Usimbaji wa maandishi

Herufi za maandishi zinawakilishwa na nambari kwenye kompyuta. Mifumo tofauti ya usimbuaji hutumia nambari tofauti kwa wahusika:

ASCII

The ASCII (American Standard Code for Information Interchange) encoding uses 7 bits to represent 128 characters, including English letters (both uppercase and lowercase), digits, and common punctuation symbols. Each ASCII character can be represented by a unique number between 0 and 127.

UTF-8

UTF-8 ni usimbaji wa herufi za urefu tofauti ambao unaweza kuwakilisha kila herufi katika kiwango cha Unicode. Inatumia ka 1 hadi 4 kwa kila mhusika. UTF-8 inaendana nyuma na ASCII, ikimaanisha kuwa herufi 128 za kwanza za UTF-8 zinafanana na ASCII.

Mchakato wa Ubadilishaji

Kubadilisha maandishi kuwa desimali kunahusisha hatua zifuatazo:

  1. Determine the numerical value of each character using the chosen encoding (ASCII or UTF-8).
  2. Convert each character to its corresponding decimal (base-10) value.
  3. Kwa hiari, tenganisha kila thamani ya desimali na nafasi ya usomaji.

Mfano: Badilisha "Hi" kuwa Decimal

Step 1: Convert each character to its numerical value (ASCII):

H → 72

i → 105

Step 2: Combine the decimal values (with spaces):

72 105

Vidokezo vya Matumizi

  • When using ASCII encoding, any character outside the 7-bit ASCII range (128-255) will be converted to a question mark (?).
  • Usimbaji wa UTF-8 unaauni herufi zote za Unicode, ikiwa ni pamoja na alama maalum, emoji na herufi kutoka lugha zisizo za Kiingereza.
  • Kila herufi ya UTF-8 inaweza kuwakilishwa na maadili mengi ya desimali ikiwa inatumia zaidi ya baiti moja.
  • Maadili ya desimali mara nyingi hutumiwa katika kompyuta kwa shughuli za nambari na uwakilishi wa data.
