CodeSonar ships with library models that allow it to functions such as libm acos() that have a parameter whose value should not be greater than 1. If one of these functions is called with a value greater than 1 in the relevant parameter position, a warning will be issued.
If you have created a custom library model for some function f() in terms of one of these existing models, calls to f() will also be capable of triggering Argument Too High warnings.
English (en)
#include <math.h>
double call_acos(double ind){
double a = acos(1); /* ok */
double b = acos(2); /* 'Argument Too High' warning issued here */
double c = acos(ind); /* EVIDENCED ONLY: 'Argument Too High' warning issued here
* if CodeSonar has evidence that call_acos() is called on a value >1. */
return a+b+c;
}
