Currency format without fractional values

[raoulb]

The function lang.FormatCurrency works as expected with 2 or more decimals:

{{ 123 | lang.FormatCurrency 4 "EUR" }} -> 123,0000 €

Sometimes one might wish to get outputs like 123 € f.e. for readability concerns.
These calls:

{{ 123 | lang.FormatCurrency 0 "EUR" }} -> 123,00 €
{{ 123 | lang.FormatCurrency 1 "EUR" }} -> 123,00 €
{{ 123 | lang.FormatCurrency 2 "EUR" }} -> 123,00 €

all give two digits. Instead I would expect the following:

{{ 123 | lang.FormatCurrency 0 "EUR" }} -> 123 €
{{ 123 | lang.FormatCurrency 1 "EUR" }} -> 123,0 €
{{ 123 | lang.FormatCurrency 2 "EUR" }} -> 123,00 €

If for some reason this is not possible, one should extend the documentation explaining precision >= 2.

Duplicate of #8858.

Addressed with #8950.

If you think the documentation needs additional clarification, please create an issue or pull request in https://github.com/gohugoio/hugoDocs. Thanks.

Never mind. Hidden in plain sight!

Still unfortunate that we can't resolve the "stylistic printing" issue as explained in #8858.
