Option for human-readable format

[arkel-s]

First, thanks for this great tool!

For large code bases, the numerical output are hard to read, example:

It would be nice to get an option for human readable format, like 72.9 M (or 72.9e6)

That sounds useful. Do you know if there are any localisation problems with that @arkel-s ? Im not across what happens in Europe enough to determine that.

Oh yes, unfortunately there are many ways to write numbers, and no iso standard 😞
I believe that supporting this would be overkill, we can use either the UK/US way (123,456,798.01) ; scientific notation (1.23e6) or SI Prefixes, that have the advantage of being shorter.

Random copy/paste:

func LineCountDecimal(b int64) string {
        const unit = 1000
        if b < unit {
                return fmt.Sprintf("%d", b)
        }
        div, exp := int64(unit), 0
        for n := b / unit; n >= unit; n /= unit {
                div *= unit
                exp++
        }
        return fmt.Sprintf("%.1f %c", float64(b)/float64(div), "kMGTPE"[exp])
}

Using an underscore also makes them more readable.

I might just make the decision to go with the US standard on this. Maybe with the option to modify it via a flag.
