NAME

calc - simple integer calculator that accepts decimal/hex/octal and outputs decimal/hex/octal/binary

SYNOPSIS

calc [ options ]

DESCRIPTION

The calc command may be used to do simple integer calculations or to convert numbers from one radix to another.

Calc reads commands from stdin and prints the result to stdout. The input radix for numbers may be decimal (default), octal (if starting with a '0') or hexadecimal (if starting with "0x"). The output is always printed in four radixes: decimal, octal, hexadecimal and binary. The decimal variant is printed as signed and as unsigned representation.

The result is printed in two variants using 32 bit and 64 bit representations for the numbers.

INPUT FORMAT

Calc accepts three types of input lines:

one number

The input line is one number only.

In this case the number is converted only to the different output formats.

unary operator

The input line is a unary operator followed by a number

In this case the unary operator is applied to the number and the result is printed in all output formats.

binary operator

The input line is a number followed by a binary operator followed by a second number.

In this case the binary operator is applied to the numbers and the result is printed in all output formats.

OPERATORS

+

-

&

%

Binary arithmetic remainder from division.

/
