Hello,
In the MathUtils class, there are a few assert statements. Most of them
are commented out, except the two following ones:
public static boolean equals(float x, float y, int maxUlps) {
// Check that "maxUlps" is non-negative and small enough so that
// NaN won't compare as equal to anything (except another NaN).
assert maxUlps > 0 && maxUlps < NAN_GAP;
...
}
public static boolean equals(double x, double y, int maxUlps) {
// Check that "maxUlps" is non-negative and small enough so that
// NaN won't compare as equal to anything (except another NaN).
assert maxUlps > 0 && maxUlps < NAN_GAP;
...
}
Since asserts are often not enabled, these assers are no-op. They also
are somewhat misleading since setting maxUlps to 0 is in fact possible
and produces in correct results: it means we do an exact comparison and
should be allowed.
I propose to change the "maxUlps > 0" into "maxUlps >= 0" and either
1) comment out the corresponding asserts (just as the other ones in
the file are commented out)
2) replace the asserts by a real test and throw a
MathIllegalArgumentException
3) remove the asserts without replacement
I would prefer choice 1.
What do you think ?
