# is more efficient than constantly rounding up to 64-bit or
# 32-bit precision as specified in the source, the compiler,
# especially in the optimized mode, tries very hard to keep
# values in x87 floating-point stack (in 80-bit precision)
# as long as possible. This has important side effects, that
# the real value used in computation may change depending on
# how the compiler did the optimization - that is, the value
# kept in 80-bit is different than the value rounded down to
# 64-bit or 32-bit. There are possible compiler options to
# make this behavior consistent (e.g. -ffloat-store would keep
# all floating-values in the memory, thus force them to be
# rounded to its original precision) but they have significant
# runtime performance penalty.
#
# -mfpmath=sse -msse2 makes the compiler use SSE instructions
# which keep floating-point values in SSE registers in its
# native precision (32-bit for single precision, and 64-bit
# for double precision values). This means the floating-point
# value used during computation does not change depending on
# how the compiler optimized the code, since the value is

# It's commonly useful to pass |this| to objects in a class'

# on the passed-in pointer (until later), and annotating every legit
