Character Codes

This page contains the character codes used internally by the calculator. This table can be useful in particular with the char() and ord() commands.

Characters in the following ranges can be used for variable names:

  • 48…57 (numbers, as long as they don't begin a variable name)
  • 65…90, 97…122 (the usual alphabet, case insensitive)
  • 128…139, 141…148, 181 (Greek letters, case sensitive: ω is not the same as Ω)
  • 192…214, 216…246, 248…255 (international characters, case insensitive)

Note that value 2 (STX) cannot be used on the home screen, because for some reason it does not exist in large font.
