For example, a fixed-point representation with a uniform decimal point placement convention can represent the numbers 123.45, 1234.56, 12345.67, etc, whereas a floating-point representation could in addition represent 1.234567, 123456.7, 0.00001234567, 1234567000000000, etc.

What is the difference between fixed-point and floating-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.
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 is floating-point representation with example?
Representation of floating point number is not unique. For example, the number 55.66 can be represented as 5.566×10^1 , 0.5566×10^2 , 0.05566×10^3 , and so on. The fractional part can be normalized. In the normalized form, there is only a single non-zero digit before the radix point.
Which is an example of floating numbers?
A floating point number, is a positive or negative whole number with a decimal point. For example, 5.5, 0.25, and -103.342 are all floating point numbers, while 91, and 0 are not.
