floating point 32 bit to 16

someone know the way to convert the floating
point 32 bit to floating point 16 bit??

Thanks in Advance

not anymore, but i know the code was somewhere on the nvidia page. i guess you can find it in the cg package somewhere in the sources…

visit http://www.openexr.org

there you can find the SDK for the OpenEXR image format, an image format with 16 bit (half) float per channel. There is also a class for converting betwen 32bit and 16bit float
