How to calculate floating point numbers, using IEEE-754 standard:


Floating point number = (-1)^Sign * (1.Fraction) * Radix^(Exponent - Bias)
Bias = 2^(k-1) -1 1.Fraction refers to Fraction bits.
Example of Calculation of 1.Fraction:
Fraction bits = 10110
1.Fraction = 1 + [1 * 2^-1] + [0 * 2^-2] + [1 * 2^-3] + [1 * 2^-4] + [0 * 2^-5]

Database Normal forms:


First Normal Form (1NF):
- All attributes contain atomic values
- Values are all of a single type per column.
- All records are unique, and can be identified by a primary key
