ABSTRACT:
A calculating apparatus comprises a memory and a calculating section. The memory is stored with table data for referencing a value of a variable x by using a value of a variable y and a value of a solution z. The calculating section inputs x_in and y_in, reads two values y_a and y_b corresponding to y_in from the memory, reads two values x_aa and x_ab corresponding to x_in from the memory in a line corresponding to y_a, reads two values x_ba and x_bb corresponding to x_in from the memory in a line corresponding to y_b, and calculates a solution z corresponding to x_in and y_in in an interpolation by using x_in and y_in and the read values y_a, y_b, x_aa, x_ab, x_ba, and x_bb.
