Hi, The image values that you mentioned show that its a gray scale image with only 256 shades of gray. So a fractional value will be quantized to the nearest integer and you'll only be able to store integars from 0 to 255. In other words by 103.234 that you are trying to store, you are defining a shade of gray which is impossible to be represented by a gray scale. With a precision ranging to 3 decimal positions, you need some thing like 65536 levels of quantization ! Btw just for your info, human eye is only sensitive to 256 shades of gray so a further resolution cannot be processed by our brains. Regards. Imran.
