To Add/Subtract or Multiply two floating point numbers in a custom format
The format is very much similar to IEEE 754 format. The floating point number is 32 bits, and the first bit is reserved for sign-bit. The following 12 bits are for exponents in 2's complement format, and the rest 19 bits are for mantissa in normalized form.
The final result is stored in the memory.
