is there such thing, or i have to write such thing myself?
i think you mean longinteger (longint)?
integer (-32768..32767)
longint (-2147483648..2147483647)

well..
For integers up to 2^64 you can use long long on C or Int64 on Pascal.. but if the numbers are much more larger you need to write it..

To write, or not to write.

Greetings!
For a 32-bit compiler like FreePascal, the big integer types and ranges are:
Check Free Pascal - Ordinal Types
If you need anything larger than that, you'll have to code it yourself
IF you know an easy way, code it.
