But the credit of expressing number through decimal fraction is awarded to the Muslim Mathematicians. Again they introduce first the irrational numbers in square root form as a solution of the quadratic equation in algebra in the 11th century. According to the historians, very near to 50 BC the Greek Philosophers also felt the necessity of irrational number for drawing geometric figures, especially for the square root of 2. In the 19th century, European Mathematicians gave the real numbers a complete shape by systematization. For daily necessity, a student must have a vivid knowledge about ‘Real Numbers’. In this chapter real numbers are discussed in detail.
