[fpc-pascal] Functions for int128rec ?

[LacaK]

Hi,
I noticed that there is "int128rec" type, but I do not found any support 
routines which can do operations like multiplication, addition with this 
type.
Is there something or is planed any integrated support in FPC for "int128" ?
(To be precise I need convert large integer (larger than int64) stored 
in TBCD to their binary representation; something like BCDToInteger(), 
but result type should be "int128rec")
Thanks
