question: public void testConstructorStringRadix8 ( ) { String value = "76356237071623450" ; int radix = 8 ; byte rBytes [ ] = { 7 , - 50 , - 28 , - 8 , - 25 , 39 , 40 } ; BigInteger aNumber = new BigInteger ( value , radix ) ; byte resBytes [ ] = new byte [ rBytes . length ] ; resBytes = aNumber . toByteArray ( ) ; for ( int i = 0 ; i < resBytes . length ; i ++ ) { assertTrue ( resBytes [ i ] == rBytes [ i ] ) ; } assertEquals ( "incorrect sign" , 1 , aNumber . signum ( ) ) ; }
target:  Create a positive number from a string value and radix 8.
