convert_eng - Convert numbers to and from engineering notation
convert_eng [options] number number ...
Options:
+help verbose help
+pref format a number using SI prefixes
+ez explicitly display 'e0'
+unf unformat: convert a string back to a number
Format a number (or a list of numbers) using engineering notation. Formatted/converted values will be printed to STDOUT, one per line.
Note that the options use +, instead of a conventional dash, so that negative numbers can be converted. All options can be abbreviated.
To format a floating-point numeric value using SI prefixes, use the +pref option.
convert_eng +pref 1e-16
To convert a string formatted with an SI prefix back to a numeric value, use the +unf option.
convert_eng +unf 77M
By default, if the exponent is zero, e0 is not displayed. To explicitly display e0, use the +ez option. This option has no effect if +pref is used.
convert_eng +ez 22.2
