As Andrey suggests, a fairly obvious way of dealing with the data is to check the min/max values and do a linear scaling between them, but some applications will do substantially more complex things to make the information viewable.
That makes sense. So, there's no such thing as a "standard way" to deal with floating-point samples with no S[MIN,MAX]SAMPLEVALUE information, unless you know how the image was generated and for what purpose. When you don't, then the linear scaling seems to be a good enough solution.
