/series/{id}: show the prices in the same way everywhere

[php-coder]

At present the prices from catalogs and in sellers/buyers block use different ways of displaying and hence they look different (1 vs 1.00 and 1.1 vs 1.10):

We should decide on what way of formatting we're using and use it everywhere.

@cssru WDYT?

I like my approach because it looks more clean and less verbose. In the same time I like your solution because it uses standard utils from Thymeleaf.

I suggest to use two digits after point.
1.5 EUR looks weird for me :)

1.5 EUR looks weird for me :)

Hmm.... Why? It's obvious for me :)

[cssru]

'cause there is not one euro and a half. 'cause there is one euro and 50 cent.

[php-coder]

Ok, I agree with that.

But I don't like to see 80.00 RUB instead of 80 RUB. WDYT about this case then?

[cssru]

Ok. 80.56 and 80.00 looks in one style, but 80.56 and 80 - in different and then uncool :)

[cssru]

I suggest to ask for some accountant :)

[php-coder]

I've just asked my wife (she is an accountant) that's why I agreed on 80.50 :) But here is a different area -- we're more close to a shop than to a bank. We don't need to be so strict here and it's better to be human-oriented. For example, I believe that the prices in the shops will look like 80 (instead of 80.00) and 80.5 (instead of 80.50). But maybe I'm wrong here.

[cssru]

Is I remember prices look like 80.00 written on special tickets. Maybe, in your country they look different?

[cssru]

To be closer to reality we should write "two ground bucks" :)

Commit 9287473 (#884) added yet another place where prices are shown: /collection/{slug}/estimation.

After rewriting to JavaScript/React we might use browser's internationalization: https://blog.bitsrc.io/new-intl-apis-in-javascript-c50dc89d2cf3
