Evgueni Souleimanov f68eb7c9fd fix "warning: comparing floating point with == or != is unsafe" (epsilon comparison)
Instead of comparing floats "x == y", perform comparison
"fabs(x - y) <= epsilon", where epsilon is acceptable error that
accumulates in computation of x and/or y.

Because in this case all integers are small and all floats are exactly
representable under IEEE754, epsilon may be zero in our tests.

This warning occurred when compiling using

gcc (GCC) 4.4.7 20120313 (Red Hat 4.4.7-3)

on CentOS 6.5 x86_64

using the following CFLAGS (locally inserted into Makefile)

CFLAGS = -g -Wall -Wextra -Wformat=2 -funsigned-char -fstrict-aliasing
 -Wstrict-aliasing -Wfloat-equal -Wundef -Wuninitialized -Wpointer-arith
