    摘要： The disclosure relates to an arm holder for a pole-handled tool such as a broom, a mop, a squeegee, etc. that allows effective use of the pole-handled tool with only one hand. The arm holder comprises an arm grip having an arm-holding structure; and an attachment portion capable of attaching the arm grip to the pole-handled tool; wherein the arm-holding structure is capable of receiving an arm positioned within the arm-holding structure while a corresponding hand of the same arm grasps the pole handle, the pole handle acting as a lever where the corresponding hand forms a fulcrum of the lever.

    摘要： An embodiment of an apparatus performs a floating-point multiply-add process on a first multiplicand, a second multiplicand, and an addend. A leading 0 bit is added to a mantissa of the first multiplicand to form an expanded first mantissa, and a partial-product multiplication is performed on the expanded first mantissa and a mantissa of the second multiplicand to produce partial-product sum and a partial-product carry mantissas. Leading bits of the partial-product sum and carry mantissas are changed to 0 bits if they are both 1 bits, and the partial-product sum and the partial-product carry are shifted right according to an exponent difference of a product of the first multiplicand and the second multiplicand. Otherwise both the partial-product sum and carry mantissas are arithmetically shifted right according to the exponent difference. The first and second multiplicands and the addend can be complex numbers.
