MYC(1)

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.

OPERATORS
myc understands the following binary infix operators (from highest priority 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 complement).

DATA TYPES
myc knows three data types:

boolean,

integer
    (32 bit),

float
    (64 bit, equivalent to C double).

NOTES
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.
