A radio-frequency surgical implement detection system detects surgical implements in a surgical wound during and at the completion of a surgical procedure. Surgical implements, including surgical sponges or laparotomy pads, gauze pads and metallic surgical instruments, are individually attached to a non battery-powered, encapsulated radio-frequency marker. The marker comprises an integrated chip having a burnt-in memory code, which is broadcast through an antenna using a modulated carrier frequency. The code is received by an interrogating antenna of a detector. The interrogating antenna provides a power pulse, which is received by the antenna of the radio-frequency marker. The power pulse charges a capacitor, which proves power for the read function, carrier frequency modulation function and broadcast function of the integrated chip, permitting each marker-containing implement to be specifically identified.

A decimal multiplication mechanism for fixed and floating point computation in a computer having a coefficient mechanism without resulting leading zero detection (LZD) and process which assumes that the final product will be M+N digits in length and performs all calculations based on this assumption. Least significant digits that would be truncated are no longer stored, but retained as sticky information which is used to finalize the result product. Once the computation of the product is complete, a final check based on the examination of key bits observed during partial product accumulation is used to determine if the final product is truly M+N digits in length, or M+N−1 digits. If the latter is true, then corrective final product shifting is employed to obtain the proper result. This eliminates the need for dedicated leading zero detection hardware used to determine the number of significant digits in the final product. The corrective final product shifting also incorporates adjustments to the coefficient of the product when the product's exponent is at its extremes and the final product must be brought to be within the precision and range of a given format.
