2.20.5.use the %E in printf() to display scientific-notation numbers

#include <stdio.h>

 

int main()

{

    float lightyear = 5.878E12;

    float jupiter = 483400000;

    float distance;

 

    distance = jupiter/lightyear;

 

    printf("Jupiter is %E light years from the sun.\n",distance);

 

    return(0);

}

Jupiter is 8.223886E-005 light years from the sun.
