       binary2ascii - Convert binary numbers to textual representation


       binary2ascii [flags]


       binary2ascii reads input consisting of binary numbers and converts them
       to their textual representation.  Command line flags specify  the  type
       and  size  of the binary numbers and provide control over the format of
       the output. Unsigned integers may be  written  out  in  binary,  octal,
       decimal,  or  hexadecimal.  Signed  integers may be written out only in
       binary or decimal.  Floating point numbers may be written out  only  in
       decimal,  either  in  standard  or scientific notation. (If you want to
       examine the binary representation of floating point numbers, just treat
       the input as a sequence of unsigned characters.)


       Long options may not be available on some systems.

       -b|--base <base>
              Base     for     integer    conversions:    b(binary),d(ecimal),
              h(exadecimal), o(ctal), or 2,8,10, or 16.

              Delimit the output as  per  the  locale.  Without  this  option,
              floating  point  numbers  will  have  a  decimal  point  and  no
              separation of groups, integers no delimiters at all.  With  this
              option,  the  decimal  separator will be chosen according to the
              locale (which, for example, may  make  it  a  comma),  and  non-
              fractional digits will be grouped and separated according to the
              rules for the locale in force. For American English, this  means
              groups  of  three digits separated by commas, whereas for German
              in Germany it means groupsof three digits separated by  periods.

              Do not delimit the output as per the -d option.

              Use exponential (scientific) notation.

              print help message

              add  a  linefeed  after  every  0x0A  value if the size is char,
              short, int, or long, that is, the sizes that might  represent  a

       -L|locale <locale>
              Set the LC_NUMERIC facet of the locale to <locale>.

       -n|--number <number>
              number of items to print per line.

       -o|--offset <offset>
              byte offset at which to start.

       -p|--precision <precision>
              the precision to use when printing floating point numbers.

              print sizes of types on current machine and related information

       -t|--type <type>
              set type and size of input

              do not mark hexadecimal output with the prefix 0x.

              be verbose.

              print version information.

              minimum field width.

              print a summary of the exit status codes.

              zero pad on left.

              do not zero pad on left


       The  following  are  the possible input types. Note that some types may
       not be available on some machines.

       d  double

       f  float

       q long double

       sc signed char

       ss signed short

       si signed int

       sl signed long

       sq signed long long

       uc unsigned char

       us unsigned short

       ui unsigned int

       ul unsigned long

       uq unsigned long long


       The following values are returned on exit:

       0 SUCCESS
              The input was successfully converted.

       1 INFO The user requested information such as  the  version  number  or
              usage synopsis and this has been provided.

              An error resulted from a failure of the operating system such as
              an i/o error or inability to allocate storage.

              The program was called with invalid or inconsistent command line

       5 INPUT ERROR
              This  means that the input was ill-formed, that is that it could
              not be interpreted  as  a  number  of  the  required  type.  For
              example, if the input is 0x2A and a decimal value is called for,
              an INPUT ERROR will be  returned  since  0x2A  is  not  a  valid
              representation of a decimal integer.
