Number Format Exception (double to Long)

[Chris Cornelius]

I have an issue with trying convert a double to a Long value. I need to convert the double to Long so that it can be stored in a bean of type Long. Here is the code snippet:

double doubleAmount = 1230.45;
            String stringAmount = Double.toString(doubleAmount);
            Long longAmount = new Long(Long.valueOf(stringAmount));

I am getting the following exception:

java.lang.NumberFormatException: For input string: "1230.45"


What am I missing?

Thanks in advance.

Long does not include decimals. If that's what you want, you can cast a double to a long and chop off the decimal :

double doubleAmount = 1230.45;
Long longAmount = (long)doubleAmount; // boxing to Long (java5 only)

Thanks Christope,

So it looks like my options are to change the bean type
to either a string or double to keep the decimal intact.

Or a BigDecimal object.
