NAME
myc - a simple calculator
SYNOPSIS
myc [command]
DESCRIPTION
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 myc-command is
specified on the command-line, the result is echoed and
myc exits immediately. If invoked with no arguments, myc
starts reading commands from standard-in. myc understands
the following binary infix operators (from highest prior-
ity to lowest): ** (power), * (multiply), / (divide), %
(modulo), + (add), - (subtract), << (shift left), >>
(shift right), < (less), <= (less or equal), > (greater),
>= (greater or equal), == (equal), != (not equal), &
(arithmetical and), | (arithmetical or), ^ (arithmetical
exclusive or), && (logical and), || (logical or), =
(assign); and the following unary prefix operators: -
(negate, unary minus), ! (logical not), ~ (bitwise com-
plement). myc knows three data types: boolean, integer
(32 bit), 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
4/7. instead of 4/7 or a/(b+0.) instead of 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 $$ and $n where n is the
number of the command.
