hi guys

I have a method like this
public static String getAmount(String amt){
            String value = "";
            Long longVal = Long.parseLong(amt)* 100000000000;
            value = ""+longVal;
            return value;
      }

when amt is "45.65" , it throws numberformatexception.
any ideas how i can resolve this ?

thanks very much

4.65 is not a Long value. Use Float.parseFloat or Double.parseDouble for floating point values.

Long is the data type for a long integer, and 45.65 is not an integer.

Change Long to Double or BigDecimal, these are data types that can handle the fractional numbers.
