Code examples

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

#include <stdint.h>

void func()
{
  float       l = 2.4l;
}

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

#include <stdint.h>

void func()
{
  uint32_t    a = 0U;
  int64_t     c = 0L;
  uint64_t    e = 0UL;
  uint32_t    g = 0x12bU;
  float       i = 1.2F;
  float       k = 1.2L;
}
