 * @assertion It is a compile-time error if the unbounded integer value of a

 * double-precision value, assuming that the mantissa is extended with zeros
 * until the precision is sufficiently high to unambiguously specify a single

 * integer value of a double valued integer literal with binary representation
 * of 54 bit length can be represented exactly as an IEEE 754 double-precision
 * value (if the most significant bit is 1 and the low bit is 0).
