Option to force sub-whole digits for whole inputs

[mcandre]

Hi,

I am using go-humanize for some backend code and BenjaminVanRyseghem/numbro for frontend code. Unfortunately, these libraries have slightly different semantics when humanizing numbers, resulting in different reports depending on where data is processed.

For example, go-humanize always omits sub-whole digits when applying SIWithDigits(input, 1, units), while numbro(input).format('0.0a') always keeps sub-hole digits.

I have asked numbro to make trailing .0 optional in the output. That would at least match how go-humanize behaves.

Meanwhile, it would also be helpful for go-humanize to provide an option to keep sub-hole digits in SI text, as another way to get these libraries working in sync.

How would such an option be expressed?
