A device and methods are disclosed for communicating an unrounded result from one arithmetic calculation for use in a second, subsequent calculation. For example, an unrounded result of a first calculation can be forwarded to provide a multiplier, a multiplicand or an addend operand for the subsequent operation. The operand can be forwarded to the input of the same fused multiply addition module (FMAM) that supplied the result, or to another FMAM, and do so without regard to the precision of the forwarded operand, the precision of the subsequent operation, or the native precision of the FMAM.
