I have not identified any as yet. I did verify however that there are no uses
in `open/src/**/*.java` of either `absExact()` or `negateExact()`,

@rgiulietti Actually your trick is the

Thanks. I was thinking of leveraging the
Sorry, typo
int q = x / y;
if ((x & y & q) >= 0) {
return q; // q, not r
}
throw new ArithmeticException("integer overflow");

No idea about relative perf.

Are there examples in the JDK or its tests

Note: The `StrictMath` equivalents were
Please consider this proposal to add `divideExact()` methods for integral data
types to `java.lang.Math` thereby rounding out "exact" support to all four
basic arithmetic operations.
