I want to delete the decimal point of the amount(V10)

Nice to meet you all.
I use directory theme and micro job theme in Japan.

I want to provide the service only in Japan, so I only display it in JPY(Japanese Yen), but there is one problem.
Japanese Yen does not need to be priced after the decimal point.

So, I don’t want to display “.00” after the decimal point. Where should I set it?

If anyone knows, please let me know.

I’m using Version 10, but for some reason it says Version 9. I do not know why.
