Function not in current scope

ROOT
1

Hi all,
I tried to use “polar” function (#included ) in a script, for example exp.cpp.

If I input

g++ exp.cpp
./a.out
then everything goes fine.
But if I input
root exp.cpp
then
Error: Function polar(1.3,3.14) is not defined in current scope exp.cpp:11:
*** Interpreter error recovered ***

How to solve this? Thanks for any help or advise!

Regards,

It works for me.

root [0] .x exp.C
(-1.3,0.00207045)
root [1]

where exp.C is:

#include <complex>

void exp() {
   cout << polar(1.3,3.14) << endl;
}

Hi couet,
Thanks but it still doesn’t work for me.
Is it relevant to version?

Yes, may be it is worth trying a more recent version.
