Extra 0 print in float on windows

I have a program which shows a different print (an extra 0 on windows) and i am trying to make it same as linux . On windows using Visual studio 2012 . On linux using g++ v4.8.3

Any sugegstion .

I have created a small program to showcase problem that I am facing ...

#include "stdafx.h"

#include <stdio.h>

int main()
{

 float f = -1e-14;
 printf("\n\n  \t Lets print the float value  -1e-14  as  [%9.3g]  \n\n\n\n",f);  

return 0;
}

On linux : 

/home/mag>./a.out


         Lets print the float value  -1e-14  as  [   -1e-14]

On windows :(notice extra 0 in -1e-014)

         Lets print the float value  -1e-14  as  [  -1e-014]

Reason why I am trying to make it same is because I am debugging some output from windows and linux and huge amount of differences between outputs of windows and linux are due to the problem stated above and I am missing important differences because of these .

Call _set_output_format(_TWO_DIGIT_EXPONENT) first to cause printf() to use two-digit exponents with VS2012.
