Instructions

  1. Provide text or data for this tool.
  2. Choose decimal byte output.
  3. Compare the output with a known Decimal Encoder sample.
  4. Keep the original value until the receiving system accepts the result.

Example

Input: Hi

Settings: Decimal Encoder: choose decimal byte output

Result: 72 105

Limits

  • Decimal Encoder: decimal output can be confused with a single number
  • Decimal Encoder: The operation does not detect a different input format automatically.
  • Decimal Encoder: Processing stays in the browser.

Questions

How do I show the decimal value of each byte?

Supply the data and select a delimiter. The tool writes each input byte as a decimal value. It does not combine the complete input into one large decimal integer.

Why do some decimal byte values become negative?

Support signed values reads bytes as signed eight-bit integers. Values with the high bit set then use the negative range. Disable that option when the receiving system expects unsigned values from 0 through 255.

Does one text character always produce one decimal value?

No. A text encoding can use several bytes for one character. This operation displays bytes rather than Unicode character codes. Use Charcode Encoder when you need the character value instead of its encoded bytes.
