Conversion from Long to Double in Java
You could simply do :
double d = (double)15552451L;Or you could get double from Long object as :
Long l = new Long(15552451L);double d = l.doubleValue();
As already mentioned, you can simply cast long to double. But be careful with long to double conversion because long to double is a narrowing conversion in java.
e.g. following program will print 1 not 0
long number = 499999999000000001L; double converted = (double) number; System.out.println( number - (long) converted);
