steps for hao to install and use plong lib in place of float/double in c++ programs :

1. cd install
2. run install script as : ./install_plong.sh (if not permitted then run : chmod 755 install.sh)

~/maigit/eclp/plong/install $ ./install_plong.sh
installing cplong library.
copying libplong.so in /usr/lib/ directory. may need your sudo permission
copying cplong.h in /usr/include/ directory. may need your sudo permission
finished installing.  to use library, add '-lplong' as a flag

1. if install_plong.sh ran successfully then in c++ programs ve can use cplong as

   1. in our programs(say sample.cpp) ve need to include cplong as : #include <cplong.h>
   
   2. when compile program using g++ ve need to use -lplong at end as:	
   
   3.g++ -c sample.cpp -lplong
   
   4. if makefile is used then have variable LOADLIBES = -lplong at top of makefile
   
   4. for sample usage ve can see test programs vritten in tests folder.
   '''
   
   

2. to run testcases for this lib

   
   1. go to plong/tests directory
   
   2. ~/plong/tests $ ./run
   
   

vhy to use plong library instead of float/double :

repl.it clang build command :

clang++-7 -pthread -std=c++17 -o main src/cplongekseption.cpp src/cplong.cpp src/main.cpp

linux g++/clang++ build command :

1. ~/maigit/eclp/plong $ clang++ -o main src/cplongekseption.cpp src/cplong.cpp src/main.cpp
2. ~/maigit/eclp/plong $ g++ -o main src/cplongekseption.cpp src/cplong.cpp src/main.cpp

####historical instances oph india oriznl nmbr system : pach rupaiye barah aana

= pach rupaiye + barah aana

= (5, 0) + (Q, -1)

= (5, 0).dec_pl(-1) + (Q, -1)

= (50, -1) + (Q, -1)

= (50+Q , -1)

= (5Q, -1)

= 5Q:1 string representation 1 here means 1 layer belo 0th precision layer.
