[ASTERIXDB-2999][RT] Round towards zero when convering floating-point to integer
- user model changes: no
- storage format changes: no
- interface changes: no
Details:
- Remove use of Math.floor() during floating-point to integer conversion.
The conversion code now rounds both positivie and negative values towards zero
- Update index selection code to account for this change
- Add SqlppNumericIndexRQGTest to randomly test different combinations
of indexes on numeric fields

> Fix integer constructors handling of negative double/float numbers

> Key: ASTERIXDB-2999
> URL: https://issues.apache.org/jira/browse/ASTERIXDB-2999
> Project: Apache AsterixDB
> Issue Type: Bug
> Components: RT - Runtime
> Reporter: Dmitry Lychagin
> Assignee: Dmitry Lychagin
> Priority: Major
>
> Currently bigint() and other integer constructors round down its input
> double/float number which is not what user might expect for negative values.
> (i.e currently bigint(-1.1) returns -2, not -1).
> We need to change it to round towards zero instead. (bigint(-1.1) should
> return -1)
