Register Value with separation of thousands hundred and cents

Hello,
where or how do I program values to appear as follows $ 00,000.00
Today if I put a value for example $ 90,990 it appears to me on the product page at auction as $ 90.99 $
If you put $ 90,990.00 He will unset everything and does not appear correctly
and how do I remove the $ symbol in front of the value, that is, the right side?

I’m from Brazil and I would like to see it in the following format
R $ 00,000.00
