    • A device and a method for calculating an inverse square root are provided to easily and quickly calculate a correct result while reducing latency and an occupied area by properly using an LUT. The first LUT(110) stores the first approximation of a mantissa part of the inverse square root of a real number, and outputs the first approximation by referring to an exponent and mantissa part of the real number. The second LUT(120) stores the second approximation of the mantissa part of the inverse square root of the real number, and outputs the second approximation by referring to the exponent and mantissa part of the real number. A multiplier(130) multiplies the second approximation and the exponent part output from the second LUT. A subtractor(140) outputs the imaginary part of the inverse square root of the real number by subtracting a multiplication result from the first approximation output from the first LUT. An exponent operator operates and outputs the exponent part of the inverse square root of the real number.
