Commit ID 94a3608ab9f2334784ac3b111dc79c9eb5e33ba3
Author Marco Costalba

Fix GrainSize rounding error The rounding formula is different between positive and negative scores due to the GrainSize/2 term that is asymmetric. So use truncation instead of rounding. This guarantees that evaluation is rounded to zero in the same way for both positive and negative scores. Found with position's flip bench: 4634244
