    • Method Detail

      • multiply

        public final void multiply​(float[] src,
                                   float factor,
                                   float[] dst)
        Multiplies two words by one word to produce a result of three words. Most significant word is stored first.
        Parameters:
        src - Source array, first multiplicand.
        factor - Second multiplicand.
        dst - Destination array.
      • compare

        public final float compare​(float[] src1,
                                   float[] src2)
        Compares three words. Most significant word is stored first.
        Parameters:
        src1 - First operand.
        src2 - Second operand.
        Returns:
        Less than zero if src1 < src2, greater than zero if src1 > src2 and zero if src1 == src2.
      • add

        public final float add​(float[] src,
                               float[] srcDst)
        Adds three words. Most significant word is stored first.
        Parameters:
        src - First operand.
        srcDst - Second operand, and destination of the operation.
        Returns:
        Overflow carry bit.
      • subtract

        public final void subtract​(float[] src,
                                   float[] srcDst)
        Subtracts three words. Most significant word is stored first.
        Parameters:
        src - First operand.
        srcDst - Second operand, and destination of the operation.
      • divide

        public final float divide​(float[] srcDst)
        Divides three words by the base to produce two words. Most significant word is stored first.
        Parameters:
        srcDst - Source and destination of the operation.
        Returns:
        Remainder of the division.
