  2. Select base 16 as the output radix.
  3. Compare the output with a known Base Encoder sample.
  4. Keep the original value until the receiving system accepts the result.

Example

Input: 255

Settings: Base Encoder: select base 16 as the output radix

Result: ff

  • Base Encoder: Processing stays in the browser.

Questions

How do I convert a decimal number to another base?

Enter a decimal number and select the destination Radix. The result expresses that number in the selected numerical base. This operation converts a numeric value; it does not encode a text message as Base64.

Why does the result contain letters?

Bases above 10 need more digit symbols than 0 through 9. The output uses letters for those additional values. Select the same radix when you convert the result back to decimal.

Can I use base conversion for a fixed-width identifier?

Only if you also handle the required width. Numeric notation does not retain leading zeros or the original formatting. Compare the recovered numeric value, and add padding separately when a destination requires it.
