int is useless

In PHP, maybe. We're talking about GS2 here, so we have to assume that it's going to screw up easily with large decimals, as seen when it can't correctly subtract 8 from 7.999969482. Obviously, it's rounding 7.999969482 to 8, which is also why int(7.999969482) returns 8 instead of 7.

I did a quick test on RC. int(7.999) returns 7, but int(7.9999) returns 8. int(7.9998) returns 7, as well as int(7.999899999). Considering that 7.9999 and 7.999969482 have one thing in common, it's safe to assume that when Graal sees ".9999", it'll round up to the nearest whole number.

What are you trying to accomplish, exactly? Perhaps if you showed us the problem in context, somebody might be able to figure something out (unless you're fine with using your work-around).
