[Rd] sprintf of big int

[Sokol Serguei]

Hi,

I wanted to print a big integer value in hexadecimal format with sprintf() but could not (cf. here 
after). As R supports integer values upto 2**53-1 (storing them in a double) is it possible to make 
sprintf() to work on such big values?

Best,
Serguei.
