List of modInverse() Examples

Examples of modInverse()

java.math.BigInteger.modInverse()
Returns a BigInteger whose value is {@code (this}^-1 {@code mod m)}. @param m the modulus. @return {@code this}^-1 {@code mod m}. @throws ArithmeticException {@code m <= 0}, or this BigInteger has no multiplicative inverse mod m (that is, this BigInteger is not relatively prime to m).
