NAME
       rax2 -- radare base converter

SYNOPSIS
       rax2 [-ebBsSvxkKh] [[expr] ...]

DESCRIPTION
       This command is part of the radare project.

       Rax2  is	a powerful calculator within the Radare2 suite,	primarily used
       for numerical system conversions, encoding and decoding C strings, hex-
       pairs, and base64, essential for	binary analysis	and reverse  engineer-
       ing tasks.

       The  most common	numerical bases	include	binary (base 2)	for direct ma-
       chine code interaction, hexadecimal (base 16) for memory	addresses  and
       compact	data  representation, and decimal (base	10) for	human-readable
       calculations and	interpretations.

OPTIONS
       -a	   Show	ASCII table

       -b	   Force output	mode (numeric base)

		     f	  floating point
		     2	  binary
		     3	  ternary
		     8	  octal
		     10	  decimal
		     16	  hexadecimal

       -c	   Show	hexadecimal C string from integer value

       -C	   Dump	stdin to C array in stdout (xxd	replacement)

       -d	   Print the result in decimal (base 10)

       -D	   Decode the input data using base64

       -e	   Swap	endianness

       -E	   Encode the input data using base64

       -f	   Interpret the input number as a 32bit dword and display  it
		   using IEEE 754 standard for floating	point arithmetic

       -F	   Read	C strings from stdin and output	in hexpairs. Useful to
		   load	shellcodes

       -h	   Show	usage help message

       -k	   Keep	the same base as the input data

       -K	   Show	randomart key asciiart for values or hexpairs

       -H	   Convert a string into a hash

       -i	   Convert LONG	to/from	IP ADDRESS

       -j	   Show	 the  output  in  json	format,	the same as the	r2 `?j
		   0x804` command.

       -n	   Append newline to the decoded output	for human friendlyness

       -o	   Convert from	octal string to	char (rax2 -o 162 62)

       -q	   Be quiet. Show less information or drop the superfluous de-
		   tails in the	output.	For example: rax2 -qC

       -r	   Show	the same output	as the r2's `? 0x804`  command.	  When
		   combined  with  -S (-rS) it will print r2 commands to write
		   the actual binary into radare2

       -s	   Convert from	hex pairs string to character (rax2 -s	43  4a
		   50)

       -S	   Convert from	character to hex string	(rax2 -S C J P)

       -t	   Convert epoch timestamp to human readable date format

       -u	   Convert given value to human	readable units format

       -v	   Show	program	version

       -w	   Display the result as 16bit signed integer value

       -x	   Show	hexpairs from integer value

       -X	   Convert  a  bit stream (an arbitrary	sequence of 0 and 1 of
		   any length) to hexadecimal. The result can be  larger  than
		   64bits

       -z	   Convert from	character string to binary (rax2 -z hello)

       -Z	   Convert from	binary string to string	(rax2 -l 01000101)

USAGE
       Available variable types	are:

	 int   ->  hex	  rax2 10
	 hex   ->  int	  rax2 0xa
	 -int  ->  hex	  rax2 -77
	 -hex  ->  int	  rax2 0xffffffb3
	 int   ->  bin	  rax2 b30
	 bin   ->  int	  rax2 1010d
	 float ->  hex	  rax2 3.33f
	 hex   ->  float  rax2 Fx40551ed8
	 oct   ->  hex	  rax2 35o
	 hex   ->  oct	  rax2 Ox12 (O is a letter)
	 bin   ->  hex	  rax2 1100011b
	 hex   ->  bin	  rax2 Bx63

EXAMPLES
       With  no	 arguments,  rax2 reads	values from stdin. You can pass	one or
       more values as arguments.

	 $ rax2	33 0x41	0101b
	 0x21
	 65
	 0x5

       You can do 'unpack' hexpair encoded strings easily.

	 $ rax2	-s 41 42 43
	 ABC

       It supports some	math operations:

	 $ rax2	1+1 "0x5*101b+5"
	 2
	 30

       Encode and decode binary	file using base64:

	 $ rax2	-E < /bin/ls > ls.b64
	 $ rax2	-D < ls.b64 > ls

	 $ cmp /bin/ls ls && echo $?
	 0

       Use -z/-Z to convert between binary and string:

	 $ rax2	-z hello
	 001100000111100000110001001100010011001000110011
	 $ rax2	-Z 0110100001100101011011000110110001101111
	 hello

       It is a very useful tool	for scripting, so you can read floating	 point
       values,	or get the integer offset of a jump or a stack delta when ana-
       lyzing programs.
