About Programming Language Tools
Pasting a hex constant into source code means matching the exact syntax that language expects. This category converts hex values into integer literals for Python, JavaScript, C, and other languages, so you can drop a constant straight into your code.
Frequently Asked Questions
Do all programming languages write hex literals the same way?
No — most use a 0x prefix (Python, C, JavaScript), but the exact integer size limits and casing conventions differ by language.
Why would I convert hex to a language-specific integer?
To paste a constant — like a color value or bitmask — directly into source code without manually retyping or reformatting it.
Does the target integer type's size matter?
Yes — a hex value that fits in a 32-bit int can overflow a smaller type, so match the literal's size to the variable it's going into, especially in strictly-typed languages like C.
What if my language isn't listed here?
Most C-family and C-derived languages (Java, C#, Go, Rust, Swift) accept the same 0x-prefixed hex literal syntax as C, so a C integer conversion is usually a safe starting point even without a dedicated page.
