.It Fl N
Show hexadecimal C string from integer value
.It Fl u
Convert given value to human readable units format
.It Fl v
Show program version
.It Fl x
Convert a string into a hash
.It Fl h
Show usage help message
.El
.Sh USAGE
.Pp
Force output mode (numeric base)
.Pp
  =f    floating point
  =2    binary
  =3    ternary
  =8    octal
  =10   decimal
  =16   hexadecimal
.Pp
Available variable types are:
.Pp
  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
.Pp
With no arguments, rax2 reads values from stdin. You can pass one or more values
as arguments.
.Pp
  $ rax2 33 0x41 0101b
  0x21
  65
  0x5
.Pp
You can do 'unpack' hexpair encoded strings easily.
.Pp
  $ rax2 \-s 41 42 43
  ABC
.Pp
And it supports some math operations.
.Pp
  $ rax2
  0x5*101b+5
  30
.Pp
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 analyzing programs.
