ABSTRACT:
According to a presently preferred embodiment of the present invention, a method for interfacing a floating point-based process with an integer-based process is described, the method having the steps of providing a floating point process, providing an integer process, initiating a transfer of data from said floating point process to said integer-based process, the transfer having the steps of selecting a memory location containing a floating point value to be handed off to the integer-based process, determining whether the memory location contains a positive number or a negative number, computing the absolute value of the value in the memory location, adding a magnitude of 0.5 to the absolute value, multiplying, if the result of the determining step was negative, the results of the adding step by -1, and converting the results of the multiplying step to integer form.
