Usage

rescale-cli [OPTIONS] VALUE1 VALUE2 ...

There is also an alias rescale, which works the same as rescale-cli

Description:

The script takes a series of numeric values and adjusts them proportionally to fit within a specified full value (default 100).

The result is output in the specified format (array, row, or line).

If the adjusted values don't exactly match the full value due to rounding, a warning message will be displayed showing the difference.

Note:

The full value must be a positive integer.

The options can be specified anywhere in the argument.
