Abstract
Disclosed are an electronic device and a controlling method. The method of controlling an electronic device includes: converting a first polynomial into a first sub-polynomial based on each term and coefficient of a first polynomial, and converting a second polynomial into a second sub-polynomial based on each term and coefficient of a second polynomial; acquiring a calculated sub-polynomial by performing a multiplication operation on the converted first sub-polynomial and the converted second sub-polynomial; removing coefficients greater than or equal to a preset number of digits from coefficients of the calculated sub-polynomial divided based on each term unit of the first polynomial and the second polynomial; and determining coefficients of a sub-polynomial from which the coefficients greater than or equal to the preset number of digits divided based on each term unit of the first polynomial and the second polynomial are removed as coefficients of a polynomial acquired by the multiplication operation of the first polynomial and the second polynomial.
