Hi Marcel,

And why not:

int delta = abs(old - new);

(unless there is no abs() in bionic)

I remember that abs() needs -lm or something stupid.

From my tests, it does not require any extra libraries other than

libc6 (at least in recent versions). It seems that at least for x86 it
is even optimized to a few machine instructions (as I could not find
the library call when using objdump on code that does
"abs(atoi(argv[1]))").
