THE CANONICAL LITERATURE OF THE JAINAS
( CHAP
(iv) Thāna (X; s. 747) mentions 10 kinds of calculation which
are differently interpreted by different scholars. (v) Thāna (II, 4; s. 95), Sūriyapannatti ( VIII, 29; p. 861),
Jambuddīvapannatti (s. 18 ) and Anuogaddāra (s. 137) give us names of notational places, the last beiny Sīsa puheliyā which stands for (84 lacs)28 years, but which according
to Joïsakarandaga (v. 64-71) stands for (84 lacs) years. (vi) Uttarajjhayaņa ( XXX, v. 10, 11 ) furnishes us with the
names of powers 2, 3, 4, 6 and 12, whereas Aņuogaddāru
(s. 142) deals with successive squares and square-roots. (vii) 21 kinds of numbers are treated in Aruvgaddāra (s. 146).
In this connection Dr. Bibhutibhusan Datta says:"It wlll be noticed that in the classification of numbers stated above, there is an attempt to define numbers beyond Alef-zero....... The fact that an attenpt was made in India to define such numbers as early as the first century before the Christian era, speaks highly of the speculative faculties of the ancient Jaina mathematicians."--The Jainu School of Mathematics (p. 142) published in "Thu Bulletin of the Calcutta Mathemetical Society" (Vol. XXI, No. 2, 1929). (viii) Aņuoyaddāru (s. 131 ) supplies us with various tables of
measurement which can be compared with those given in Kautilya's Arthaśāstra and elsewhere. Further, these tables
incidentally throw light on the history of Magadha. (ix) Viāhapannatti (XXV, 3; s. 721-726), Anuogaddürı (s.
123 & 144) and Sūriyapannatti (s. 11, 25 & 100) supply us with names of several geometrical figures, plane and
solid as well. (x) Viāhapannatti (s. 91), Jīvājīvābhiyama (s. 82 & 109)
and Suriyapannatti (s. 20 ) furnish us with values of II. (xi) Sūriyapannatti' and Joïsakarandagie supply us with astro
nomical knowledge. Prof. Weber observes:
1-2 These two works along with Lokaprakasu (pt. IV) were found very useful in
understanding the knotty points of Vedängu-jyotişa. So says Mr. B. L. Kulkarni in his article entitled "fagfa fee aria tra a1944T HETT 11T 38 vast 19 " and published in Jainasatyaprakāśa (vol. VI, No. 11, pp. 418-420).
