Try:
Allow negative
× -2
+ input [the same one]

... [any other processing]

Log to Feed

I have positive and negative values - this will only fix the negative values?

Are you sure?

Do I need to log to the feed prior to the "allow negatives" in order to get the positives in the feed?

No. Why should you? What would that put into the feed?

Ah - i understand it now.  Thanks for the help

In case anyone reading this thread later does not understand, this is what happens:

Say the input value is +123:

Allow negative
    the value is not allowed, so zero is passed forwards.

× -2
    zero × -2 = zero is passed forwards.

+ input [the same one]
    0 + +123 = 123 is passed forwards.

... [any other processing]

Log to Feed
    123 is sent to the feed.

Now say the input value is -321:

Allow negative
    the value is allowed, so -321 is passed forwards.

× -2
    -321 × -2 = +642 is passed forwards.

+ input [the same one]
    +642 + -321 = 321 is passed forwards.

... [any other processing]

Log to Feed
    321 is sent to the feed.

Had the input been logged to feed immediately, before 'allow negative', then two values would have been sent to the feed in succession, first the original value and then the absolute value.
