[GiNaC-list] Automatic transformation of expressions in GiNaC

11 Jan 2017


      Hello,
       I wrote some program to do some calculations
with GiNaC. But I can see program makes some unwanted  transformations
of expressions automatically. Below is simple example. Can I avoid that
transformations?
Wanted output is sqrt(m/2).

Best regards Petrov A.B.
--------------------------------------------------------------------
Output for program:

Starting: ./test2
1/2*sqrt(2)*sqrt(m)

*** Exited normally ***

------------------------------------------------------------------

Program:

#include <iostream>
using namespace std;

#include<ginac/ginac.h>
using namespace GiNaC;

void calc_example(){
  possymbol m("m");
  ex e = sqrt(m/2);
  cout << e  << endl;
}
int main(int argc, char** argv)
{
	calc_example();
	return 0;
}
