Hello world,

I just committed the following patch to the WWW docs.

An error was reported by Gerald's script, but that seems to
have been spurious.  At least, there was no error on
revalidation.

Regards

	Thomas

Thanks.  In the description, are the integers constants truncated
or (the result of) the division?

Sorry about that!  This happens perhaps once a year and I believe
is due to a server or connection timeout somewhere.  Your change
and the page per see indeed appear fine.

The result is truncated.

real x
x = 4/5 
end

is truncated to 'x = 0'.  The remainder of 4 is tossed.
