my program deals with large integers and random numbers calculations and printing them to files.

I want to use printf() function to write in particular file using file handle and a array variable which contains all rows that i have to print. It is fine when i code like this 

 use bigint.pm   
 $File1=">xyz.txt";  
 OPEN File1;  
###  
calculations....  

####  
 print(File1 ,@array);### @array having 20 and more digits of scalars 
 close File1;

but i want to avoid use of bigint, to speed up my program and print to a file with proper format.
