Andrey Mashenkov commented on IGNITE-25820:
-------------------------------------------
core-libs/java.lang
➜ Double.toString(double) and Float.toString(float) May Return Slightly
Different Results (JDK-4511638)
The specification of these methods is now tighter than in earlier releases and
the new implementation fully adheres to it.
As a consequence, some returned strings are now shorter than when using earlier
releases, and for inputs at the extremes of the subnormal ranges near zero,
might look differently. However, the number of cases where there's a difference
in output is quite small compared to the sheer number of possible double and
float inputs.
One example is Double.toString(2e23), which now returns "2.0E23", whereas in
earlier releases it returns "1.9999999999999998E23". Another example, in the
double subnormal range, is Double.toString(1e-323) which now returns
"9.9E-324", as mandated by the new specification.

> Project: Ignite
> Issue Type: Improvement

> Labels: MakeTeamcityGreenAgain
>
> The test
> org.apache.ignite.internal.sql.engine.planner.TpcdsQueryPlannerTest.test([59]
> 59) is green on JDK 11 and JDK 17, however, it fails on JDK 21.
> The issue is a different estimated row count in a plan:
> (rows=181545469684679580) instead of (rows=181545469684679584). For some
> reason, the estimation is less by 4 rows.
> Let's investigate the reason and fix it.
