Doesn't the 'extra' section at the bottom of that link address this? Cast your number to a negative to subtract...

Just to clarify: you need to use a different lookup array for subtractions - IOW, use the formula at the bottom of the linked page, not the one at the top.

 

@Devin

See a different method (one that actually calculates, instead of looking up pre-calculated values) here:

Note that here too the formula for subtracting is different from the formula for adding.
