I ran a program like this:

```
#include <stdio.h>
int main(void)
{
float aboat = 32000.0;
double abet = 2.14e9;
long double dip =5.32e-5;
printf("%f can be written %e\n",aboat,aboat);
printf("And it's %a in hexadecimal, powers of 2 notation\n",aboat);
printf("%f can be written %e\n",abet, abet);
printf("%Lf can be written %Le\n",dip,dip);
\\ this statement can not print rightly
return 0;
}
```

but it print like this :

```
32000.000000 can be written 3.200000e+004
And it's 0x1.f40000p+14 in hexadecimal, powers of 2 notation
2140000000.000000 can be written 2.140000e+009

00000 can be written 272.500183
```

as you can see , this result must be incorrect. but I can not find error, so is it a bug attribute to IDE ? I use JetBrains CLion 2017.3.4.

thanks for remind.this is my CMakeList.txt:

```
cmake_minimum_required(VERSION 3.9)
project(untitled1 C)
set(CMAKE_C_STANDARD 11)
add_executable(untitled1 main.c)
```

And the gcc version is 6.3.0
