How to use Convert Integers to Hex Base
- 1. Paste the integers. Enter one or more decimal integers, one per line or separated by spaces. Negative values and zero are handled correctly.
- 2. Choose hex letter case. Turn on Uppercase hex letters if you want results like FF instead of the default lowercase ff, matching whichever convention your codebase or documentation uses.
- 3. Copy the hex values. Copy the hexadecimal strings and paste them into source code, memory documentation, or a color value wherever a base-16 representation is expected.
When to use Convert Integers to Hex Base
Convert Integers to Hex Base turns ordinary decimal numbers into their hexadecimal form. It is built for the frequent need to see a value's hex representation while working with memory addresses, color codes, or byte-level protocol fields.
- Building a color value from a decimal component. You calculated a red, green or blue channel value as a decimal number and need its two-digit hex form to construct a hex color code for a stylesheet.
- Preparing an address or offset for documentation. You have decimal offsets from a spreadsheet and need them written in hex to match the convention used in a memory map or datasheet you are writing.
- Checking a decimal-to-hex homework problem. A computer science course assigns manual decimal to hexadecimal conversion. Verify your calculated answers against this tool before submitting the assignment.
- Matching a codebase's uppercase or lowercase hex style. Some style guides require uppercase hex literals while others require lowercase. Toggle Uppercase hex letters to match whichever convention the surrounding code already uses.
