    • 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.
