Clamp function
From Unreal Wiki, The Unreal Engine Documentation Site
Clamp is math function provided by the Object
()class.
Limits V to the interval of [A, B]. Exactly speaking, A will be returned if V is smaller than A, B will be returned if V is larger than B, otherwise V is returned.
This also applies if A is larger than B. So if V is larger than B, but smaller than A, the value of A is returned even though V is actually between the two values.
