price format Switcher

Hi,

1) Is it possible to configure the price format as follow:
– If the convertef price is: 854 000 to display 850 000
– If the converted price is: 857 000 to display 860 000

I played with the price format, but couldn’t make it work, any help would be great!

2) Another issue is that I set 2 currency USD and Lebanese. For example, if I’m on the main page and switch to Lebanese currency, it display, when I go to another page, it reset and display default currency (USD), Why?

Thank you!
