Abstract

A data processing apparatus for performing rounding on an input value to produce a rounded form output value includes floor calculation circuitry that receives the input value in redundant-representation and generates two candidates of a floor of the input value in non-redundant representation. Ceiling calculation circuitry receives the input value in redundant-representation and generates two candidates of a ceiling of the input value in non-redundant representation. Selection circuitry outputs one of the two candidates of the floor of said input value and the two candidates of the ceiling of said input value as the rounded form output value, based on a sign of a residual value associated with the input value. Each of the two candidates of the floor of the input value correspond with different values of the sign of the residual value and each of the two candidates of the ceiling of said input value correspond with different values of the sign of said residual value.
