Subject [jira] [Commented] (LUCENE-3037) TestFSTs.testRealTerms produces a corrupt index

Yonik Seeley commented on LUCENE-3037:
--------------------------------------

committed.

Robert, your instinct to avoid floating point was good.  StrictMath would not have eliminated
all of the errors.
For example log(380204032,52) using StrictMath still returns 4, while the integer versions
correctly return 5.
