@@ -1429,15 +1429,20 @@ numbers are treated as signed unless they have a @code{U} suffix. Unsigned
integers cannot be larger than 2^64-1. If @var{n} is an unsigned integer then @var{-n}
is also a valid unsigned integer as in C. Signed integers must fall into
the [-2^63, 2^63-1] range or a correspondingly smaller range when a suffix
specifies a smaller type. Out of range signed numbers trigger a warning.
specifies a smaller type.
Ordinary @code{0x} hex integers with @var{n} hex digits (counting leading
zeros) use the smallest size of 1, 2, 4 and 8 bytes that can accommodate
any n-digit hex integer. If an integer suffix specifies a size explicitly
the corresponding number of least significant bytes are written.
Otherwise, signed and unsigned integers alike occupy the smallest of 1, 2,
4, or 8 bytes needed to accommodate them in their respective
representation.
zeros) use the smallest size of one, two, four and eight bytes that can
accommodate any n-digit hex integer. If an integer suffix specifies a size
explicitly the corresponding number of least significant bytes are
written, and a warning shown if the number does not fit into the desired
representation. Otherwise, unsigned integers occupy the smallest of one,
two, four or eight bytes needed. Signed numbers are allowed to fit into
the smallest signed or smallest unsigned representation: For example,
@code{255} is stored as one byte as @code{255U} would fit in one byte,
though as a signed number it would not fit into a one-byte interval [-128,
127]. The number @code{-1} is stored in one byte whilst @code{-1U} needs
eight bytes as it is the same as @code{0xFFFFffffFFFFffffU}.
One trailing comma at the end of data items is ignored to facilitate copy
and paste of lists.
