Hi ,

    We are using the example program in the following way.
      

	  double x = 3.0, result;
        result = sqrt(x);
         diag_printf("\nThe square root of x=%lf is result=%lf\n",
x,result);


  The Result is in the following way with out any values.

		The square root of x=%f is result=%f

Thank you,
S.Ramesh Chandra.

Could you post to the ecos list the relevant lines of code?  For
example:

	double foo; foo = sqrt(1.3324); printf("foo is %d\n",foo);

(clearly that code is wrong, but you get the idea).

And please do not just reply to me, as your reply won't go to the ecos
list, which is where we want it to go.

Hi,
  I want to use the ECOS Math Libray on ARM SAM7X Series micro
controller. I
included the MATH Library and compiled the ecos successfully.  I ran the
SQRT test.The test returns with "sqrt() is stable".

I called the sqrt function and tried to print the result,but it is
failing
to print result.

Could any one help on this issue?

Is ECOS math library supports the 'sqrt, on  ARM SAM7X series
microcontrollers?
Is ECOS supports the sqrt only on the micro controllers which has
Floating
point arithmetic support?


Thank you,
S.Ramesh Chandra.
