The `d W` (`calc-maple-language`

) command selects the
conventions of Maple, another mathematical tool from the University
of Waterloo.

Maple's language is much like C. Underscores are allowed in symbol
names; square brackets are used for subscripts; explicit ``*'`s for
multiplications are required. Use either ``^'` or ``**'` to
denote powers.

Maple uses square brackets for lists and curly braces for sets. Calc
interprets both notations as vectors, and displays vectors with square
brackets. This means Maple sets will be converted to lists when they
pass through Calc. As a special case, matrices are written as calls
to the function `matrix`

, given a list of lists as the argument,
and can be read in this form or with all-capitals `MATRIX`

.

The Maple interval notation ``2 .. 3'` has no surrounding brackets;
Calc reads ``2 .. 3'` as the closed interval ``[2 .. 3]'`, and
writes any kind of interval as ``2 .. 3'`. This means you cannot
see the difference between an open and a closed interval while in
Maple display mode.

Maple writes complex numbers as ``3 + 4*I'`. Its special constants
are `Pi`

, `E`

, `I`

, and `infinity`

(all three of
`inf`

, `uinf`

, and `nan`

display as `infinity`

).
Floating-point numbers are written ``1.23*10.^3'`.

Among things not currently handled by Calc's Maple mode are the
various quote symbols, procedures and functional operators, and
inert (``&'`) operators.
