numliststat v0.4 [30 Jul 2024] by Dominic
Description
Returns statistical value(s) for a piped-in list of numbers - integers or decimals, space or line-separated. 6 values (sum count mean median minimum maximum) are output, columnised with a descriptive header; or if one or more of these are added as parameters (case-insensitive and only the first three letters are significant, tot(al) can be used instead of sum and ave(rage) instead of mean) then only the specified value(s) are output, with no header or columnising.
Note the optional -p setting for the maximum number of decimal places in each output result (default: 4). Unless the -m setting is used, results are shown with as few decimal places as possible that give an accurate result, subject to the maximum setting (but the calculations are at a much higher level of precision).
Options
-h -see this help
-m - always show the maximum number of decimal places even when not required i.e. with trailing zero(es)
-p n - show a maximum of n decimal places for output value(s) (default: 4)
-l - see changelog

My Programs
Here is a selection of some (other) programs I have written, most of which run under GNU/Linux from the command line (CLI), are freely available and can be obtained by clicking on the links. Dependencies are shown and while in most cases written and tested on an x86-based Linux server, they should run on a Raspberry Pi, and many can run under Windows using Windows Subsystem for Linux (WSL) or Cygwin. Email me if you have problems or questions, or if you think I could help with a programming requirement.
