Check if there is get parameters

[eluser]Unknown[/eluser]
Hello.
I wonder how I can check if the number of get params is more than 0? I tried just

Code:

count($this->input->get());

but if there is not any get params the $this->input->get() becomes boolean "true". And this is quite strange for me. When there is some params it becomes an array. So now I use

Code:

if (is_array($this->input->get())

to check if there is any params, but it seems not the best solution
