XLVI
The second value of is noticed in Jambudvipaprajñaptı (sutra 19) and in Uttaradhyayanasūtra (XXXVI, 59).

In the
Digambara works T is equated to since, according to these works = V10=V9+23+ 193
RAJJU
In most of the Jaina works, a rajju is defined as the diameter of the Svayambhuramana ocean. Ratnasañcayaprakarana (v. 4835, p. 189°) defines rajju as follows:
A god can go 100,000 yojanas in the winking of an eye. The distance which he can go in 6 months is a rajju.
Rajju is also defined as under:
If a powerful god were to throw down forcibly an iron ball heated and weighing 1000 bhāras, the distance which it can cover in 6 months, 6 days, 6 praharas, and 6 ghatikās is equal to a rajju. See Ratnasancaya (v. 19–207).
1 This leads us to infer that the Jainas were aware of the fact that the circumference of a circle varies as its diameter.
2 Cf. Lokaprakās'a (I, v. 72).

3 According to The Jaina Gem Dictionary (pp. 154-155), the rule for finding a sq. root is to write the sq. root of the nearest rational number and to add to it the remainder divided by twice its sq. root e. g. V=Vi+2V = 1 + 3. Cf. VN-Va2+r= a + where r is small. 4 Cf. Lokaprakas'a (I, v. 65).
