Fix snapping test failing on 32-bit platforms (hopefully)

The discrepancy between the results seems to come from floating point arithmetics (-mfpmath option in GCC) which defaults to different values: - '387' for i386 - 'sse' for x86-64 The 387 coprocessor temporarily uses 80-bit precision so the results of arithmetic operations may be a bit different
