hi,
Thanks for the stimulating thoughts...
I would personally expect to see the output data type be the same as the
*first* argument. I find that to be more consistent within REBOL (i.e. try
appending a path to a block, now a block to a path) so if you have an integer
and you subtract, add, divide.... it should affect the integer not the
percent. and if you are dealing with a number besides 100, it should be as
you said, "per cent" example:
>> 200 - 50%
== 100
>> 500 + 100%
== 1000
>> 100 - 75%
== 250
After all, if you don't evaluate it that way, you have lost the advantage
that you get from the datatype, or at least the most obvious reason that I
can see (what did you have in mind to use it for Andrew?).
Give me a point of view that would logically result in a different result
than I have given. (I am often too blind to the things around. ;-) and
while you are at it, please explain why 100 * 50% would result in a percent!
rather than an integer.
Thanks!!
