## Definition

This `AdaptableUnaryFunction` computes the total degree of a `PolynomialTraits_d::Polynomial_d`.

Given a (multivariate) monomial the sum of all appearing exponents is the total degree of this monomial. The total degree of a polynomial \( p\) is the maximum of the total degrees of all appearing (multivariate) monomials in \( p\).

For instance the total degree of \( p = x_0^2x_1^3+x_1^4\) is \( 5\).

The total degree of the zero polynomial is set to \( 0\). From the mathematical point of view this should be \( -\infty\), but this would imply an inconvenient return type.
