Examples of java.math.BigInteger.abs()

java.math.BigInteger.abs()
Returns a BigInteger whose value is the absolute value of this BigInteger. @return {@code abs(this)}

        int nbits = RubyNumeric.num2int(n);
        BigInteger val = this.value;
        if (val.signum() >= 0) {
            return newBN(getRuntime(), val.shiftLeft(nbits));
        } else {
            return newBN(getRuntime(), val.abs().shiftLeft(nbits).negate());
        }
