The Blum-Shub-Smale (BSS) model of computation is introduced over the real numbers to model the kind of computations done in the numerical analysis. Characteristic features of this model are the constant (unit) size for all real numbers and the unit cost arithmetic. The weak and weighted variants of the BSS model over the real closure are analyzed.
