Embodiments of the present invention may provide methods and circuits for energy efficient floating point multiply and/or add operations. A variable precision floating point circuit may determine the certainty of the result of a multiply-add floating point calculation in parallel with the floating-point calculation. The variable precision floating point circuit may use the certainty of the inputs in combination with information from the computation, such as, binary digits that cancel, normalization shifts, and rounding, to perform a calculation of the certainty of the result. A floating point multiplication circuit may determine whether a lowest portion of a multiplication result could affect the final result and may induce a replay of the multiplication operation when it is determined that the result could affect the final result.
