What is floating point number? How is it different to fixed point number? Represent (+678.001)10 and (-0.00000125)10 in IEEE 754 double precision floating point number format.

fractional binary numbers have two parts, the bits that represent the integer number (the part before the radix point) and the bits that represent the fractional part (the part after the radix point).
Think about this! What if we had only a limited number of binary bits in which to store our fractional binary number? This is common in many modern computers systems, How would we know how many bits to use for the integer part and how many bits to use for the fractional part?
This is the problem that both Fixed Point and Floating Point Notations representations attempt to solve.
To get started then, let’s take a look at Fixed Point notation. It is the simpler one of the two representations.
