I got the following BigDecimal from a Money-Object: BigDecimal 49.99 and I need this as Integer 4999, so everything I ask for is getting rid of the separator.
I could get this BigDecimal as String and remove the separator and parse it to an Integer, but I do not think that this is pretty.
BigDecimal bigPrice = moneyPrice.getValue();
Integer price = bigPrice.intValue();
Using this only responses with 49.
You need the method:
movePointRight(int n)
javadoc link: http://docs.oracle.com/javase/6/docs/api/java/math/BigDecimal.html#movePointRight(int)
example:
BigDecimal bd = new BigDecimal("398.0275");
System.out.println(bd.movePointRight(bd.scale()));
outputs:
3980275
If you want to use the number, just bd=bd.movePointRight(bd.scale());
If it's currency and always to 2 dp, you could multiple it by 100. However as Davio comments, your code should make it clear why you're doing it.
If you want to convert, for example a price in GB pounds sterling to GB pence (100 pence in a pound) then multiplying it by 100 is the right thing to do.
Try this code:
BigDecimal db = new BigDecimal("49.99");
// multiply with 10^scale ( in your case 2)
db = db.multiply(new BigDecimal(10).pow( db.scale()));
System.out.println(db.intValue());
It's not necessary to do any math on the BigDecimal; you can just call myBigDecimal.unscaledValue() to get the underlying unscaled BigInteger directly.
