Detect if a variable is a Boolean?

I’m almost finished with my project, and one thing that im trying to fix are the warnings.l I have an animator script which turns off all booleans in the animator, but it keeps saying that floats are not booleans. I just need a way to exclude these floats from the list of variables i need to turn off. Thanks in advance!

Here:

    private void AllBooleansFalse()
    {
        foreach (AnimatorControllerParameter parameter in yourAnimatorVariableHere.parameters)
        {
            if (parameter.type == AnimatorControllerParameterType.Bool)
            {
                yourAnimatorVariableHere.SetBool(parameter.name, false);
            }
        }
    }
