    摘要: A method of an aspect includes receiving a floating point scaling instruction. The floating point scaling instruction indicates a first source including one or more floating point data elements, a second source including one or more corresponding floating point data elements, and a destination. A result is stored in the destination in response to the floating point scaling instruction. The result includes one or more corresponding result floating point data elements each including a corresponding floating point data element of the second source multiplied by a base of the one or more floating point data elements of the first source raised to a power of an integer representative of the corresponding floating point data element of the first source. Other methods, apparatus, systems, and instructions are disclosed.

    摘要: A method of an aspect includes receiving a floating point rounding instruction. The floating point rounding instruction indicates a source of one or more floating point data elements, indicates a number of fraction bits after a radix point that each of the one or more floating point data elements are to be rounded to, and indicates a destination storage location. A result is stored in the destination storage location in response to the floating point rounding instruction. The result includes one or more rounded result floating point data elements. Each of the one or more rounded result floating point data elements includes one of the floating point data elements of the source, in a corresponding position, which has been rounded to the indicated number of fraction bits. Other methods, apparatus, systems, and instructions are disclosed.
