/*
 *  parseInt() tests
 *
 *  parseInt() must have "mathematically exact" results for any supported
 *  power of two radix (2, 4, 8, 16, 32).  For instance, parsing the base-8
 *  representation of 2**256 must yield the exact IEEE double value.  This
 *  is easy for base two radixes.  However, the same property is required
 *  also for base 10 (though not for other bases), which is tricky.
