[command]

.\"
.SH DESCRIPTION
.B Myc
is a simple calculator capable of all operations available in C.
Commands are entered in infix notation.  It is possible to use parentheses.
If a
.BR myc -command
is specified on the command-line, the result is echoed and
.B myc
exits immediately.
If invoked with no arguments,
.B myc
starts reading commands from standard-in.
.B myc
understands the following binary infix operators (from highest priority to
lowest):
.B **
(power),
.B *
(multiply),
.B /
(divide),
.B %
(modulo),
.B +
(add),
.B -
(subtract),
.B <<
(shift left),
.B >>
(shift right),
.B <
(less),
.B <=
(less or equal),
.B >
(greater),
.B >=
(greater or equal),
.B ==
(equal),
.B !=
(not equal),
.B &
(arithmetical and),
.B |
(arithmetical or),
.B ^
(arithmetical exclusive or),
.B &&
(logical and),
.B ||
(logical or),
.B =
(assign);  and the following unary prefix operators:
.B -
(negate, unary minus),
.B !
(logical not),
.B ~
(bitwise complement).
.B myc
knows three data types:
.BR boolean ,
.B integer
(32 bit),
.B float
(64 bit, equivalent to C double).
On some esoteric platforms the precision of integer and float may be
different.
As in C the result of a division depends on the data types of the operands.
An integer divided by an integer yields an integer.
If you want the result to be a float, make sure one of the operands is a
float, e.g. type
.I 4/7.
instead of
.I 4/7
or
.I a/(b+0.)
instead of
.IR a/b .
The power operation returns a float if the result is too large to fit in an
integer.
The result of a calculation is stored in the special variables
.B $$
and
.BI $ n
where
.I n
is the number of the command.
