If the elements in the problem are real numbers, the decision-tree lower bound extends to the real random-access machine model with an instruction set that includes addition, subtraction and multiplication of real numbers, as well as comparison and either division or remaindering ("floor").
If the elements in the problem are real numbers, the decision-tree lower bound extends to the real random-access machine model that includes arithmetic operations such as addition, subtraction, and multiplication of real numbers, along with comparison and either division or modulus ("floor") operations.
