The mayanumber package

Mayan numerals (dots and bars) and vigesimal alphabetic notation (0-9, A-J) for LaTeX, with positional floor colors in a seven-color cycle.

• Engines: XeLaTeX or LuaLaTeX. Loads xcolor and fontspec automatically.
• Font: requires the free font "BabelStone Mayan Numerals" (https://www.babelstone.co.uk/Fonts/). An alternative face (e.g. Noto Sans Mayan Numerals) can be declared as mayanumerals BEFORE loading the package; the package then skips its own declaration.
• Default output: vertical stack of glyphs, colored by positional floor (floor 0 = units at the bottom). Options: vertical|horizontal, colors|nocolor, scale=<n>, align=<c|t|b>; they combine freely. Starred form mayanumber{N} prints the alphabetic notation.
• Unlimited magnitude: base-20 conversion by long division over the decimal string, immune to TeX's 32-bit integer limit.
