overview

A floating point operation is the rounded result of the exact operation:

$\displaystyle ($ R $\displaystyle \varphi)(x,y,\ldots) =$ R $\displaystyle (\varphi(x,y,\ldots)).$

It should be noted that to implement R $\varphi$ the value $\varphi (x,y,\ldots)$ does not have to be computed exactly, but merely with sufficient accuracy to uniquely determine the result of the rounding operation.
