A SQRT calculator capable of calculation with a minimal error is provided. The integer calculation unit selects a largest integer from a set of integers with a square of each of the integers smaller than an input datum. The transformation unit transforms the selected integer from the integer calculation unit by multiplying it by 2 and shifts a decimal point of the resulting number to the right by 1 place, thereby adding a certain number less than 10 to the decimal point shifted number to calculate a transformation value. The calculation unit shifts a decimal point of the number less than 10 to the left by 2 places and multiplies the transformation value by the resulting value, thereby subtracting the multiplied value from the input datum and choosing a largest number less than 10 with the subtracted value being in a desired range as a second decimal number of the square root. Thus, the SQRT calculator is capable of calculation with minimal error and, furthermore, has a minimum size of hardware.
