I need more information about floating point sample format.

Are TIFFTAG_SMINSAMPLEVALUE (340) and TIFFTAG_SMAXSAMPLEVALUE (341) intended for use with floating point samples?

If so, than how do you scale sample values when they are not included?

Those tags aren't supposed to be used for scaling anyway - they're only for information.

(see the TIFF spec)

And they should be usable for floating point values, even if not spelled out in the original spec.
