Why is fixed-point better than floating-point?
Fixed-point computations can be faster and/or use less hardware than floating-point ones. If the range of the values to be represented is known in advance and is sufficiently limited, fixed point can make better use of the available bits.
What are the advantages of fixed-point method?
Memory Usage and Speed — In general fixed-point calculations require less memory and less processor time to perform. Cost — Fixed-point hardware is more cost effective where price/cost is an important consideration.
What is the two main advantages of floating-point vs fixed-point number representations?
Floating-point numbers have two advantages over integers. First, they can represent values between integers. Second, because of the scaling factor, they can represent a much greater range of values.
What is the difference between floating-point and fixed-point?
In fixed point notation, there are a fixed number of digits after the decimal point, whereas floating point number allows for a varying number of digits after the decimal point. This representation has fixed number of bits for integer part and for fractional part.
