SYNOPSIS
       numfmt  [--debug]  [--grouping]	[-d|--delimiter]  [--field] [--format] [--from] [--from-unit] [--to]
       [--to-unit]   [--padding]   [--header]	[--round]    [--suffix]	   [--unit-separator]	 [--invalid]
       [-z|--zero-terminated] [-h|--help] [-V|--version] [NUMBER]

DESCRIPTION
       Convert numbers from/to human-readable strings

OPTIONS
       --debug
	      print warnings about invalid input

       --grouping
	      use  locale-defined grouping of digits, for example 1,000,000 (which means it has no effect in
	      the C/POSIX locale)

       -d, --delimiter 
	      use X instead of whitespace for field delimiter

       --field  [default: 1]
	      replace the numbers in these input fields; see FIELDS below

       --format 
	      use printf style floating-point FORMAT; see FORMAT below for details

       --from  [default: none]
	      auto-scale input numbers to UNITs; see UNIT below

       --from-unit  [default: 1]
	      specify the input unit size

       --to  [default: none]
	      auto-scale output numbers to UNITs; see UNIT below

       --to-unit  [default: 1]
	      the output unit size

       --padding 
	      pad the output to N characters; positive N  will	right-align;  negative	N  will	 left-align;
	      padding  is  ignored  if	the output is wider than N; the default is to automatically pad if a
	      whitespace is found

       --header []
	      print (without converting) the first N header lines; N defaults to 1 if not specified

       --round  [default: from-zero]
	      use METHOD for rounding when scaling

	      Possible values:

		     • up

		     • down

		     • from-zero

		     • towards-zero

		     • nearest

       --suffix 
	      print SUFFIX after each formatted number, and accept inputs optionally ending with SUFFIX

       --unit-separator 
	      use STRING to separate the number from any unit when printing; by	 default,  no  separator  is
	      used

       --invalid  [default: abort]
	      set the failure mode for invalid input

	      Possible values:

		     • abort

		     • fail

		     • warn

		     • ignore

       -z, --zero-terminated
	      line delimiter is NUL, not newline

       -h, --help
	      Print help

       -V, --version
	      Print version

EXTRA
       UNIT options:

       -  none:	 no  auto-scaling is done; suffixes will trigger an error - auto: accept optional single/two
       letter suffix:

	   1K = 1000, 1Ki = 1024, 1M = 1000000, 1Mi = 1048576,

       - si: accept optional single letter suffix:

	   1K = 1000, 1M = 1000000, ...

       - iec: accept optional single letter suffix:

	   1K = 1024, 1M = 1048576, ...

       - iec-i: accept optional two-letter suffix:

	   1Ki = 1024, 1Mi = 1048576, ...

       - FIELDS supports cut(1) style field ranges:

	   N N'th field, counted from 1
	   N- from N'th field, to end of line
	   N-M from N'th to M'th field (inclusive)
	   -M from first to M'th field (inclusive)
	   - all fields

       Multiple fields/ranges can be separated with commas

       FORMAT must be suitable for printing one floating-point argument %f.  Optional quote (%'f)  will	 en‐
       able  --grouping	 (if supported by current locale).  Optional width value (%10f) will pad output. Op‐
       tional zero (%010f) width will zero pad the number. Optional negative values (%-10f) will left align.
       Optional precision (%.1f) will override the input determined precision.
