# is more efficient than constantly rounding up to 64-bit or

# 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.

# value used during computation does not change depending on
