Subject: [PATCH] Fix director_classes testcase failures on x86
Adjust the floating point constants to be 1.125 and 2.25 (which
can be exactly represented in base-2 floating point) instead of
1.1 and 2.2 (which can't). This avoids problems on platforms where
floating point calculations suffer from excess precision, the most
commonly used of which is x86 when using 387 FP instructions.
