👉 Saturations are a type of mathematical function that represents a constant value in an interval or a domain. In other words, a saturation is a specific value within a range or a set of values. Saturation can be positive, negative, or zero and it can also be linear, quadratic, cubic, quartic, or even higher-order polynomials. The concept of saturations was introduced by mathematician and physicist, Albert Einstein in his work on quantum mechanics.
