Java BigInteger modPow() method20 Mar 2025 | 2 min read The modPow() method of Java BigInteger class is used to perform modular exponentiation. This method returns a BigInteger whose value is (thisexponent mod parameter value). This method first calculates the pow() method then applies the mod() method. This method allows negative exponents. Syntax:Parameter:exponent- The Exponent. m- The modulus. Returns:This method returns (thisexponent mod m). Exception:ArithmeticException - m ≤ 0 Example 1Output: 13^2 mod 5 is 4 Example 2Output: java.lang.ArithmeticException: BigInteger: modulus not positive Example 3Output: 13^-2 mod 5 is 4 Example 4Output: -13^-2 mod 5 is 4 Next TopicJava BigInteger |
