The notation in decimals may be seen at peak denominations of time in years in Chapter IV of TPT(V). described in VV.294 et seg. They are as follows:

The above process of multiplication with 84 and 84(10)5 goes on until mahalata is obtained. Then the process of multiplication by 84 lakh or 84(10) continually gives Śrīkalpa, hastaprahelita and ultimately acalatma whose value is (10)9°(84)51 years. This is to be carried over to maximal numerate (utkyst samkhyāta), of which the process of construction has been very elaborately described by R.C. Gupta, as maximal numerate plus one, or as the first maximal innumerate. 30
It may be noted that for setting the measure of various types of sets in karma theory, there have been various types of constructed numbers as numerate, innumerate and infinite which have not been expressed to dazzling heights without any purpose. Hence it appears that the school needed a system of this decimal type in their theory:37
