Confusion regarding the range of gray levels possible in Matlab

Say I made a double image which has a range of pixel values between 0 and 1, and another the same image with a larger range (exceeding 0 and 1).
Why do both images look different if the intensity range for double images are 0-1?

What code are you using to produce these? I assume just an imshow?
The fact that the range for double is 0-1 is exactly why they look different. The second image is clipped so all values above 1 are clipped to 1 which is why the image looks brighter.
