Floating Point operations are expensive mainly because they require a separate processing unit which requires overhead to work properly. For these and other reasons, some small processors don’t support floating point arithmetic; only fixed point (each register has a “fixed” number of bits and the ALU only supports integer arithmetic). For example, if you were writing a program using a 16 bit processor and needed resolution of 1/32, your algorithm could use 5 “fractional” bits and 10 integer bits (1 bit is needed for the sign bit).

Write how you would implement this in your program.
