Coding standards

Code examples

The following code example fails the check and will give a warning:

#include <tgmath.h>
char c1, c2;

void example (void)
{
  c2 = sqrt (c1); /* Non-compliant - essentially character real type */
}

The following code example passes the check and will not give a warning about this issue:

#include <tgmath.h>

float f1, f2;

void example (void)
{
  f2 = sqrt (f1); /* Compliant - essentially floating real type */
}
