[Frama-c-discuss] postcondition of sqr function



Hello,

I tried to prove the following post conditon with Jessie but could not  
succeed
when calling

	frama-c -jessie-analysis -jessie-gui my_sqr.c

on Mac OS X (neither with alt-ergo, yices, and cvc3).
Did I miss something obvious?

Regards Jens

/*@
     ensures \result >= 0.0;
*/
double sqr(double x)
{
    return x * x;
}
