DESCRIPTION
The number utility prints the English
    equivalent of the number to the standard output, with each 10^3 magnitude
    displayed on a separate line. If no argument is specified,
    number reads lines from the standard input.
The options are as follows:
- -l
- Display the number on a single line.
number understands negative numbers
    (although they must be preceded by ‘--’ if they are on the
    command line to avoid being mistaken for options) and numbers in scientific
    notation (e.g. 1.234E+05).
