These numbers have been described by Sugreev to Raam while giving the count of his military power. Some say about this that "Sugreev meant that innumerable monkeys were coming"; while others hold the view that ancient Hindu organized their military pattern in a particular nomenclature apart from the generalized numbers.
The present Indian system is taken from Indian astrology in which every number is increased by a multiplication of ten - 1, 10, 100, 1,000, 10,000 etc. (This is called decimal system - originated from "deca" means 10). As said in verse:
Ekam dash shatam asmat sahastram ayutam tatah param laksham |
Prayutam kotim ath arbudam vrindey kharvam nikharvam cha ||
Tasmat mahaa sarojam shankum saritaam patim twat antam |
Madhyam paraadham aaryuhya ath uttaram dash gunam tathaa gyeyam ||
Leelaavatee mathematics also says:
ek dash sahastra aayut laksh prayut kotyah kramashah |
arbudam abdam kharv nikharvam mahaapadmam shankhvah tasmaat ||
nidhih cha antam madhyam parardham iti dash gunaa uttaram sangyaah |
sankhyaaya sthaanaanaam vyavahaar artham kritaah poorvaih iti ||
It means that,
one = 1
1 ten = 10;
10 ten = 1 hundred;
10 hundred = 1 thousand (Ayut)
10 thousand
100 thousand = 1 lakh
1 prayutam =10 lakh, = 1 million;
100 lakh = 1 koti =1 crore;
100 crore = 1 arbud (Arab) = 1 billion
100 arbud = 1 vrinda
100 vrinda = 1 kharv (Kharab)
100 kharv = 1 nikharv (Neel)
100 nikharv = 1 mahaa padm (Padm)
100 mahaa padm = 1 shanku (Shankh) = 1 lakh crore
100 shanku = 1 samudra
100 samudra = 1 antya
100 antya = 1 madhyam
100 madhyam = 1 paraardh
By this, the nomenclature of million, billion and trillion, was in ancient days. This may be observed by the names "Prayutam" ( a million); "arbud" ( a billion); "shanku" (a trillion) .
