This template makes it easy to convert from decimal to [[hexadecimal]].
=== Usage ===
Use: <code><nowiki>{{Hexadecimal|x}}</nowiki></code> 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 <code><nowiki>|hex</nowiki></code> will replace the base with "hex".

To opt out of the subscript, use a second parameter of <code><nowiki>|no</nowiki></code> (or equivalently <code><nowiki>|none</nowiki></code>), 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 <code><nowiki>|digit</nowiki></code>.

===Examples===
To convert a number to a base 16:
: <code><nowiki>{{Hexadecimal|0}}</nowiki></code> → {{Hexadecimal|0}}
: <code><nowiki>{{Hexadecimal|15}}</nowiki></code> → {{Hexadecimal|15}}
: <code><nowiki>{{Hexadecimal|3256}}</nowiki></code> → {{Hexadecimal|3256}}

To convert a number to a base hex:
: <code><nowiki>{{Hexadecimal|0|hex}}</nowiki></code> → {{Hexadecimal|0|hex}}
: <code><nowiki>{{Hexadecimal|15|hex}}</nowiki></code> → {{Hexadecimal|15|hex}}
: <code><nowiki>{{Hexadecimal|3256|hex}}</nowiki></code> → {{Hexadecimal|3256|hex}}

To display single digits:
: <code><nowiki>{{Hexadecimal|0|digit}}</nowiki></code> → {{Hexadecimal|0|digit}}
: <code><nowiki>{{Hexadecimal|10|digit}}</nowiki></code> → {{Hexadecimal|10|digit}}
: <code><nowiki>{{Hexadecimal|15|digit}}</nowiki></code> → {{Hexadecimal|15|digit}}

To convert an [[RGB color model|RGB color]] from decimal code to [[hex code]]:
: <code><nowiki>{{Hexadecimal|255|no}}{{Hexadecimal|165|no}}{{Hexadecimal|0|no}}</nowiki></code> → {{Hexadecimal|255|no}}{{Hexadecimal|165|no}}{{Hexadecimal|0|no}}

;Not a number input
: <code><nowiki>{{Hexadecimal|}}</nowiki></code> → {{Hexadecimal|}}
: <code><nowiki>{{Hexadecimal}}</nowiki></code> → {{Hexadecimal}}
: <code><nowiki>{{Hexadecimal|foobar}}</nowiki></code> → {{Hexadecimal|foobar}}
: <code><nowiki>{{Hexadecimal|A B}}</nowiki></code> → {{Hexadecimal|A B}}
