Conversion of an integer to an ordinal produces a string indicating the ordinal representation of the given integer n.

$\mathrm{convert}\left(0\,\'\mathrm{ordinal}\'\right)$

$''0th''$

$\mathrm{convert}\left(1\,\'\mathrm{ordinal}\'\right)$

$''first''$

$\mathrm{convert}\left(2\,\'\mathrm{ordinal}\'\right)$

$''second''$

$\mathrm{convert}\left(12\,\'\mathrm{ordinal}\'\right)$

$''12th''$

$\mathrm{convert}\left(113\,\'\mathrm{ordinal}\'\right)$

$''113th''$

$\mathrm{convert}\left(123\,\'\mathrm{ordinal}\'\right)$

$''123rd''$

$\mathrm{convert}\left(-7\,\'\mathrm{ordinal}\'\right)$

$''-7th''$

The convert/ordinal command was introduced in Maple 17.
