There's no native support for Float16 in C++, so your best option is to promote to Float32 (or CFloat32) when reading for a format where there are stored as half floats. This is for example what is done in the GTiff driver ( HalfToFloat() function in frmts/gtiff/tif_float.c ) You could add a NBITS=16 metadata item in the IMAGE_STRUCTURE metadata domain of the band(s) to reflect the original precision.
