NAME
     aamath - renders mathematical expressions as ASCII art

SYNOPSIS
     aamath [ -q | -r ] [ expression ... ]

DESCRIPTION
     aamath  is  a  program  that accepts math expressions in infix notation and
     outputs them as ASCII art renderings. Expressions can either be entered  as
     command line arguments, or supplied on standard input.

OPTIONS
     -q     Quiet mode.

     -r     More compact radicals.

EXPRESSIONS
     The simplest types of expression in aamath are constants and variables. The
     following are recognized as constants:

     number
	    A  number, optionally in scientific notation, optionally followed by
	    ellipsis. Precision is limited only by available memory, since  num-
	    bers are represented internally as strings.

     inf    Infinity.

     nabla  The nabla operator.

     ...    Ellipsis.

     A	variable  is represented by an alphabetic character, optionally followed
     by a sequence of alphanumeric characters. A variable may have a  subscript:
     these  are represented by an underline character (_) followed by an expres-
     sion. If followed by a backslash character (\), the variable name	will  be
     rendered with an over score. Variables names may also be followed by one or
     more primes (apostrophes).

     Functions are represented by the function name, which follows the same syn-
     tax  of  variable	names  (including  optional  subscripts, over score, and
     primes), followed by comma-separated function arguments  between  parenthe-
     ses. Trigonometric functions are rendered differently if they are raised to
     a	power:	the exponent will appear between the function name and the argu-
     ment.

     Matrices are represented by a sequence of expressions between square brack-
     ets; commas separate elements of the  same  row,  and  semicolons	separate
     rows.

     Other  than  the  standard arithmetic and logical operators, which obey the
     usual precedence rules, aamath also accepts the following operations:

     expr1 ^ expr1
	    expr1 raised to expr2.

     ~(expr)
	    Complex conjugate of the expression.

     expr!  Factorial of the expression.

     The following special functions are also recognized:

     sqrt(expr)
	    Square root of the expression.

     root(expr, ord)
	    Root of order ord of the expression.

     lim(expr, var -> lim)
	    Limit of expr with var tending to lim.

     int(expr, var [= from .. to])
	    Integral of expr with respect to var, optionally  with  with  limits
	    from and to.

     sum(expr, var [= from .. to])
	    Sum  of  expr for values of var in the interval. The interval is op-
	    tional.

     prod(expr, var [= from .. to])
	    Product of expr for values of var in the interval. The  interval  is
	    optional.

BUGS
     It needs a better man page.
