Description of use
Converts a 8-bit number to hexadecimal using two digits.
Useful for formating RGB color components.
Input
  • a parameter, numeric in the range 0..255 (larger numbers will wrap around)
  • subst=subst: (optional) allows to perform a permanent substitution of the internal sub-expressions (or subtemplates that may be used), and keep only the result of the evaluations when saving a page using this template. You should pass this parameter in addition to calling the template using the "subst:" prefix that just performs a permanent template expansion and permanent substitution of parameters. (See examples below).
Output
  • a two-digit hex number
Examples
  • {{Hex2|0}}gives 00
  • {{subst:Hex2|0|subst=subst:}} gives 00
  • {{Hex2|123}} gives 7B
  • {{subst:Hex2|123|subst=subst:}}gives 7B
  • {{Hex2|255}} gives FF
  • {{subst:Hex2|255|subst=subst:}} gives FF
See also
  • {{Hex3}} for formating 3 RGB components at once.
