How to make angle limit?

i think clamp angle is for amount of rotation.
i want As only rotate up to 70 degrees.

You can use the ‘float in range’ node to limit you’re angel within -70 to +70.
Or you can also get the absolute value of your angle and then apply clamp on it and it 'll do the same thing as ‘in Range’ node.
Hope that helps.

thanks for comment.
i try it!!
