Using Realm.io to store money values

Question

I\'m starting to play with Realm.io in an Android app that I\'m writing. In one of my data objects, I\'m required to store a currency value. Previously I had stored the valu

Answer 1

What I do is store it as long

I have defined in my application a constant like so:

public static final BigDecimal MONEY_PRECISION = new BigDecimal(1000);

and when I need to store a big decimal it goes like this:

public class MoneyClass extends RealmObject {
    long _price = 0;

    public void set_price(BigDecimal price) {
        this._price = price.longValue() * App.MONEY_PRECISION.longValue();
    }

    public BigDecimal get_price() {
       return new BigDecimal(_price).divide(App.MONEY_PRECISION, 0, 0);
    }

}

In theory this should be faster than saving it on strings , but I haven't really looked at the realm code much
