QuestionMath problem with C code Pin

Just FYI, this is NOT a repost.
As usual I have posted the original in WRONG pew.
However, I found another even weirder failure of simple math case and I really do not have a clue what I am doing wrong.
Are my local variable assignments incorrect ?
Is "printf" lying to me ?

Here is the entire test code
#define MAX_CIRCLES 5

struct TAG_Circles {
	float radius;
	float center;
	float center_x;
	float center_y;

} REAL_Circle[MAX_CIRCLES], IMG_Circle[MAX_CIRCLES];

void OpenGL_Stencil_Circle_Build(void);
// copy last circle to stencil
void OpenGL_Stencil_Circle_Build(void) {
	//
	int index = 5;
	{
		// last circle
		float radius = IMG_circle[index].radius;
		float center_x = IMG_circle[index].center_x;
		float center_y = IMG_circle[index].center_y;
		printf("\n Last circle #%i  radius struct %f radius  %f", index,
				REAL_Circle[index].radius, radius);
		printf("\n Last circle #%i center_x  struct %f center_x  %f", index,
				REAL_Circle[index].center_x, center_x);
		printf("\n Last circle #%i center_y  struct %f center_y  %f", index,
				REAL_Circle[index].center_y, center_y);

	}
}


Here is the output
Last circle #5  radius struct 0.065789 radius  0.131579
Last circle #5 center_x  struct 0.000000 center_x  0.118421
Last circle #5 center_y  struct 0.000000 center_y  0.000000


The questions are NOT what I am trying to accomplish with the code ,
the questions are:

1. why values printed FROM struct DO NOT match assigned values ?
2. why is "radius" TWICE of the value assigned from struct?

PS
Only
radius struct 0.065789
is of correct value.

Cheers
