# Numeratio Indica

**Numeratio Indica** in usu est in Asia Meridionale (India, Pakistania, Bangladesha, Nepalia, Taprobane). In numeratione Vedica nititur, in qua numeri super 9 999 globis duobus et non trium ut alibi scribuntur. Non solum in linguis vernaculis Indiae, sed etiam in dialecto Anglico Indiae, vocabula *lakh* (100 000) et *crore* (10 000 000) saepe usurpantur ad numeros magnos exprimendos. Verbi causa, in India 150 000 rupiarum fit 1.5 lakh rupiarum, "₹1,50,000" vel "INR 1,50,000" scriptum; 30 000 000 (tres milliones) rupiarum fit 3 crore rupiarum, ₹3,00,00,000 scriptum; 1 000 000 000 (billio) rupiarum fit 100 crore rupiarum, ₹1,00,00,00,000 scriptum.

## Usus separatorum

In numeratione Indica, praeter tres ultimos numeros, secundum quisque numerum virgula divitur, sic:

| Numeratio Indica | Numeratio Arabica |
| --- | --- |
| 5,05,000 | 505 000 |
| 12,12,12,123 | 121 212 123 |
| 7,00,00,00,000 | 7 000 000 000 |

## Nomina numerorum

Hic index utitur scala brevis, in qua 1 billio = 1 000 000 000, et non scala longa, in quo 1 billio = 1 000 000 000 000. In India autem, praeter numerationem Indicam ambae scalae aliquando usurpantur.
