PROBLEM TO BE SOLVED: To provide a vector processor, with which high-accuracy arithmetic processing is performed by reducing an error caused by exponent matching in the case of adding different exponents. SOLUTION: Concerning the vector processor provided with at least one vector register and an adder for applying total sum operating processing to vector data in the relevant vector register, this device is provided with a data relocating means for relocating vector data in the vector register, and total sum operating processing is performed by successively inputting the data relocated by the relevant data relocating means to the adder and adding the data in order from the element of a smallest key value.
