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.
