/// @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.
/// @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
