anglosphere has million and billion with nothing in between, and we have a crore.
How about crillion to bridge their gap?
I wonder what would happen if we simply start using crillion on SM.
The number of sub denominations in any number system can only be optimally defined when each sub division holds equal power of use.
Such an optimally defined divisional system is used to divide currency denominations into numbers as direct decimal multiples of 1,2,5. (Like 10,20,50 and 100,200,500)
As such, western number system provides a strong jerk when going from thousands to millions.
Weightage is given to geometric division of rate 10 initially (as in 10s, 100s, 1000s) and then abruptly shifting to rate of thousands (10³, 10^6, 10^9 and so on).
As compared to this, the Indian system provides a step change more gradually going from
1) rate of 10(10s, 100s, 1000s)
2] rate of 100( laksham, koti, arv, nikharv, neel, padm, shankh being 10^17) and then
3) moving to the much higher rate of 10^5 (mahakoti etc) providing numbers for astronomical calculations in verbal use.
