Template:Base16 template makes it easy to convert from decimal to hexadecimal.
Usage
Use: {{Base16|x}} where x is the decimal number to be converted to a hexadecimal. Decimals and fractions will be rounded down. The number is, by default, formatted with a final subscript 16 to display the base. An optional second parameter of |hex will replace the base with "hex".
To opt out of the subscript, use a second parameter of |no (or equivalently |none), which also forces the display of at least two hexadecimal digits (instead of just one for values lower than 16).
To show a single digit, without the subscript and without the 0 prefix, set the second parameter to |digit.
Examples
To convert a number to a base 16:
{{Base16|0}}→ 016{{Base16|15}}→ F16{{Base16|3256}}→ CB816
To convert a number to a base hex:
{{Base16|0|hex}}→ 0hex{{Base16|15|hex}}→ Fhex{{Base16|3256|hex}}→ CB8hex
To display single digits:
{{Base16|0|digit}}→ 0{{Base16|10|digit}}→ A{{Base16|15|digit}}→ F
To convert an RGB color from decimal code to hex code:
{{Base16|255|no}}{{Base16|165|no}}{{Base16|0|no}}→ FFA500
