I was wondering if libtiff supports floating point format tiff? I am interested in both floating point grayscale images and floating point RGB images?

Just set TIFFTAG_SAMPLEFORMAT to SAMPLEFORMAT_IEEEFP and you can read and write single-precision IEEE floats. There's also a SAMPLEFORMAT_COMPLEXIEEEFP, but I've not used it myself.
