* The auto-Decimal promotion applies to decimal literals whose mantissa has

|
* 16+ significant digits AND whose value the double cannot reproduce
|
|
* exactly. Exponent digits, leading zeros and trailing mantissa zeros carry
|
|
* no precision; hex/octal/binary literals fold to their exact numeric value
|
|
* like Zend; and a Decimal-classified literal meeting a float-typed
|
|
* expression demotes to its exact double instead of failing to compile.
