'''Wii VC Round-to-Zero''' refers to an emulation inaccuracy in the [[Virtual Console|Wii Virtual Console]] (Wii VC). When converting a double precision floating point number (a "double") to a single precision floating point number (a "float"), the N64 typically uses the round-to-nearest rounding mode. This means that if the double is not exactly equal to a float, it will round up or down to the float that is closest in value to the original number. While this behavior is accurately emulated by most emulators and the Wii U VC, the Wii VC instead uses the round-to-zero mode. This mode will always round the double up if it is negative, and round it down if it is positive. | '''Wii VC Round-to-Zero''' refers to an emulation inaccuracy in the [[Virtual Console|Wii Virtual Console]] (Wii VC).
