       ascii2binary - Convert ASCII numbers to binary

       ascii2binary [flags]

       ascii2binary  reads  input  consisting of a sequence of ASCII
       textual representations of numbers, separated by  whitespace,
       and  produces  as  output  the  binary equivalents.  The type
       (unsigned integer, signed integer, or floating point  number)
       and size of the binary output is selected by means of command
       line flags. The default  is  unsigned  character.   Input  is
       checked  both for format errors and to ensure that the number
       requested can be represented in a  number  of  the  requested
       binary type and size.

       The  input  formats  supported are exactly those supported by
       strtod(3) for  floating  point  numbers,  by  strtoll(3)  for
       signed  integers,  and  by strtoull(3) for unsigned integers,
       except that, unlike strtod(3) floating point numbers may have
       thousands  separators.   This  means that by default integers
       may be decimal, octal,  or  hexadecimal,  determined  by  the
       usual  conventions.  The  command line flag -b may be used to
       specify another base for integer conversions.

       Long options may not be available on some systems.

       -b,--base <base>
              set base in range [2,36] for integer conversions.  The
              base may be either an integer or:





              print help message

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

              print  sizes  of  types on current machine and related

       -t,--type <type>
              set type and size of output

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

              d  double

              f  float

              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

              identify version

              print a summary of the exit status codes.

       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 sys‐
              tem  such  as  an  i/o  error or inability to allocate

              The program was called with  invalid  or  inconsistent
              command line flags.

       4 RANGE ERROR
              This  means that the input may be well-formed but can‐
              not be represented as the required type. For  example,
              if  the  input  is  the string 983 and ascii2binary is
              requested to  convert  this  into  an  unsigned  byte,
              ascii2binary  will exit with a RANGE ERROR because 983
              exceeds the maximum value representable in an unsigned
              byte, which is 255.

       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.
