________________ 118 little greater than the correct value of π (down to two numbers /figures, following the decimal point). In Jain scriptures we also find π =162/92 i.e. 256/81. There is not much difference between this value of and √10. Moreover, showing the method of finding the circumference from the diameter of the circle, the Acārya named Virasēna said that the circumference of the circle can be got by multiplying the diameter by 16 and dividing the product by 113 and adding to the result thrice the diameter. The value of π thus" obtained is 355/113. It is a real surprise that it is entirely correct down to six digits subsequent to the decimal point. It is very surprising that in the solution to the problem of squaring the circle, found by Śrīnivāsa Rāmānujan, an Indian mathematician this value of π is found. If the area of a circle is 140,000 square miles,the length of a side of its related square is only one inch larger than its definite mathematical length. 12 This value of π was familiar in China also. Possibly, it went to China with the chinese travellers/visitors Hu-en-sang, Fahyan etc. after the times of king Ashoka. 13 The Indian mathematician, Śrīnivāsa Rāmānujan has also given new formulae regarding the value of 1: (1) (2) π = π= 63 25 X Jain Education International 92 + Scientific Secrets of Jainism 17+15√√5 07 +15√5 192 22 3.14 15 92 65 26 2. The first of these two values is true down to nine digits after the decimal point, whereas the second value is true down to eight digits after the decimal point. Recently, two years ago, a scientist has found on computer the definite value of π down to 170 hundred thousand digits after the decimal point. 15 It is a matter of pride for India that formula of Śrinivasa Ramanujan, the famous mathematician of India, was used in this calculation.
