This does not alter the "content" of the standard and only alters the grammar.
The version does not, therefore, have to change.
This may have a negative value or be more than 64-bit digits long.
This is simply not expected to be interpreted as a unit of time on a computer (but nothing stops it from being interpreted).
- The technical forms are limit to 64-bit unsigned for technical use but should technology advance to a point where larger bits are needed then this allows for that.
+ The technical forms are limited to 64-bit unsigned for technical use but should technology advance to a point where larger bits are needed then this allows for that.
The systems should expect 64-bit and larger bits would have to become common before something larger than 64-bit is the expected or assumed default.
Negative signs can be allowed but they must not prevent the full use of the 64-bit.
The implementation of how this is done is left to the implementer except that the signs are immediately to the left of the digit.
