One needs to be careful when reading in data without decimal points to S.
For example,
	1833008*2154246/2172348
evaluates to
	771.15
whereas
	1833008/2172348*2154246
evaluates (as was intended) to
	1817734

Apparently multiplication of integers is done mod 2^32, whereas on division
integers are changed to reals (of course, there is a separate integer
divide if one wants to actually do that). I find this feature a bit
disturbing, as I often work with data that are recorded in integer format,
but really will be treated as real.
