RE: how to create unsigned hexadecimal initial value

["Peter Lunde" <peter_lunde@xxxxxxxxxxx>]

Richard et al:

For signed numbers, X"FFFFFFFF" is -1.
X"80000000" is a very large negative number.
So the number line goes
X"80000000" to X"FFFFFFF" to x"00000000" to x"7FFFFFFF"

For unsigned numbers, the line should go
X"00000000" to X"FFFFFFFF".

If we think about smaller numbers (one byte),
then signed numbers range from -128 to 0 to 127
and unsigned numbers range from 0 to 255.

Peter.
