Pixel depth

Here, you can see the Cellsize (10 ft x 10 ft, an area of 100 ft^2).
Pixel Type is floating point (meaning decimal places can be stored).
Pixel Depth is 32 Bit (floating-point values can range from -3.402823466e+38 to 3.

This is known as pixel depth, or image depth. For example, a one bit image contains two colours, black and white, because there are two variables in a data bit, "0" or "1".
