There are two things that made me read this code multiple times:
1) There is a parenthesis around the first conditional, but not
around the second conditional. This is inconsistent, and makes
you assume that the return value should be treated differently.
2) There is no need to explicitly write != 0 in a conditional.
Remove the superfluous parenthesis and != 0.
No functional change intended.
