Read the full guidelines for asking questions. To perform arithmetic operations on variables of type byte or short, you must enclose the expression in parentheses (inside of which operations will be carried out as type int), and then Blessings, Chetan Stan James (instanceof Sidekick) Ranch Hand Posts: 8791 posted 8 years ago Shouldn't explicitedly be explicimately? keep in mind that the compiler told-you-so, and you forced it anyway. http://stackoverflow.com/questions/20161139/type-mismatch-cant-convert-from-double-to-int-java

Now, the real Java's cast operators are enclosed by parenthesis. share|improve this answer edited Sep 19 '08 at 12:44 answered Sep 17 '08 at 9:16 Brad Richards 5831516 I guess is due to performance. So they force you to cast to narrow the value back down to byte/short. Never post a screenshot of your code!

Does it just take the long value taxTotal and convert it to a string in the $###.###.## format (or whatever format came after the () in line 2)? Why does Java not allow direct arithmetic operations on these types? (The answer is not "loss of precision", as there is no apparent reason to convert to int in the first If you want an arbitrary power of an integer, you could use a simple loop. So you get an int value as the result of these operations which Java can't safely convert back to the smaller byte and short data types.
