How is a null value typically treated in a raster operation?

What is the scope of a raster operation? In most systems, a NULL value is returned when it appears as any input of an operation, unless there are explicit instructions to ignore NULL values.

What decides the number of unique values that can be represented in a cell in raster datasets?

The pixel depth, or bit depth, determines the range of values that a particular raster file can store, which is based on the formula 2^n where n is the pixel depth. For example, an 8-bit raster can have 256 unique values, which range from 0 to 255.
