formatting of currency values in kmmsplits table

[Jack]

Just found this:   
https://trulyfinancial.com/blog/lowest-currencies-2022/  The Indonesian  
rupiah is apparently only the third weakest currency in the world with  
14,365.5 to the dollar.  The Iranian Rial is 42,250 to the dollar, but  
at 1/3 the value of the rupia, it looks like ten digits should still be  
enough.
