1,18,142 units: l'incredibile numero con due virgole

Leggendo notizie economiche della stampa indiana, mi sono trovato di fronte alla strana notazione X,XX,XXX (dove X rappresenta una cifra qualunque), come questa: "Domestic passenger car sales declined by 18.56 per cent to 1,18,142 units in August".

Se la notazione non fosse ripetuta, vedi la pagina moneycontrol, avrei potutto penesare ad un errore di stampa. 

Invece:

Da dove viene? Che significa?

Ecco un'analisi della cosa.

Domestic car sales down 19 pc, bikes' dip by 8 pc in Aug

«(PTI) Domestic passenger car sales declined by 18.56 per cent to 1,18,142 units in August 2012 compared to 1,45,066 units in the same month in 2011.»

Rifaccio i conti citati: vedo, partendo dalla vendita del 2011 di 1,45,066 (che interpreto come 145 066 unità) quanto ottengo vendendo il 18% in meno:
    145066 × (100-18,56) = 118141.75    
quindi il numero scritto nei quotidiani indiani come 1,18,142 è pari a 118 142.  

According to the data released by the Society of Indian Automobile Manufacturers (SIAM), motorcycle sales in last month fell by 8.46 per cent to 7,66,127 units from 8,36,887 units in the same month previous year.

    836887 × (100- 8,46)/100 = 766111.47

Total two-wheeler sales in August 2012 decreased by 4.50 per cent to 10,57,925 units from 11,07,782 units in the same period of previous year.

However, total sales of commercial vehicles rose by 3.92 per cent to 66,767 units from 64,248 units in the year-ago period, SIAM said. 

Come vedrete poi, in un numero che non avrebbe bisogno di nessuna virgola (o punto) nell'articolo ne mettono addirittura due!
