 * @assertion It is a compile-time error if the unbounded integer value of a
 * double valued integer literal cannot be represented exactly as an IEEE 754
 * double-precision value, assuming that the mantissa is extended with zeros
 * until the precision is sufficiently high to unambiguously specify a single
 * integer value.
 * @description Checks that it is no compile-time error if the unbounded integer
 * value of a double valued integer literal can be represented exactly as an
 * IEEE 754 double-precision value. The unbounded integer 18446744073709551616
 * has the exact double value represented as 0x43F0000000000000.
