How to adjust precision of Commaf

[Light-Wizzard]

humanize.Commaf(float64(1.1234567890), 2)
strconv.FormatFloat has a precision, just add and int like:
since you can not overload you could copy the func and rename it Commafp
that way it does not break.
Also noted that this is not localized; not that hard to localize the comma and period.

func Commafp(v float64, prec int) string {
...
parts := strings.Split(strconv.FormatFloat(v, 'f', prec, 64), ".")

Update: This does the same thing: CommafWithDigits
