 02-25-2008, 02:54 PM #1 mook MIB     Join Date: Aug 2004 Location: Los Angeles Quick Question on 'Less Than 1/3 HP' Yep, time for another question! This one should be pretty quick though. If you are at "less than 1/3 HP", your Move and Dodge are halved. Assuming a character with HP 10, would that be: A) 1/3 of 10 = 3.3, rounded down to 3 - "less than 3" is 2, so Move and Dodge are halved at HP 2 B) 1/3 of 10 = 3.3 - "less than 3.3" is 3, so Move and Dodge are halved at HP 3 I'm reasonably sure it's A, but just wanted to check before moving forward.

I somehow always thought that you only round numbers after performing all the calculations.

 02-25-2008, 04:00 PM #4 AstralRunner   Join Date: Apr 2006 Re: Quick Question on 'Less Than 1/3 HP' Rounding is not even needed in this case; the answer is 3. But, the question remains if a better example is used. Suppose the character has 12 HP, which makes 1/3 HP an integer, 4. The answer is still 3, since it is the largest possible HP value less than 4. If the character advances to 13 HP, then they suffer those effects at 4. This is one of those cases where the rule is actually "well-defined" in a mathematical sense, but confusion results because people aren't sure if they're allowed to apply regular math to game numbers. Confusion like this is inevitable when a game presumes to redefine how basic operations like rounding work.
 02-25-2008, 05:51 PM #5 mook MIB     Join Date: Aug 2004 Location: Los Angeles Re: Quick Question on 'Less Than 1/3 HP' The consensus seems to be that no rounding should occur at all, so that would mean that Move and Dodge are halved as follows: HP 09, when HP = 2 HP 10, when HP = 3 HP 11, when HP = 3 HP 12, when HP = 3 HP 13, when HP = 4 HP 14, when HP = 4 HP 15, when HP = 4 HP 16, when HP = 5 HP 17, when HP = 5 HP 18, when HP = 5 Sound about right? I'll start checking over my examples again. :) __________________ How to Be a GURPS GM, author Game Geekery, Blog (GURPS combat examples, fillable PDF sheets, rules summaries, campaigns and one-shots, beginners' intro) GURPS Discord, unofficial hangout and real-time chat

Do you have an concrete example with book and pagenumber?

I also always assumed 2!

It is quite clear, that 14/2 = 7 and that "above HP/2" is 8 in that case.
So, "below HP/2" will be 6

For 13/2 = 6.5, i always assumed 5 for "below HP/2" and 7 for "above HP/2"

And now think about how clear some rules in GURPS are written - not clear enough, it seems.

[...] or to calculate injury or other combat results, round all fractions down. For instance, for an attack that inflicts 3 points of injury with a 50% damage bonus, round down from 4.5 to 4 points." For me, that sounds like "10/3" = 3.333 = 3 And less then 3 is 2 - as long as you have 3 HP left, you will move normally! __________________ 4E books: Basic, Powers, Fantasy, Magic, Thaumatology, High Tech, Ultra-Tech, Martial Art, Supers, Space (SC only), Spaceships plus GCA and 66 of 3E books PDF: 4E as above plus Bio-Tech, DF and more

However, B419 clearly states that in this case you round up. The examples on B421 shows it's the same for 'crippling' thresholds.

GURPS always seems to assume basic math, which is pretty clear on how 3 is less than 10/3...

On B419, are you referring to where it says "Halve your Move and Dodge (round up)"? I'm assuming that's referring to the halving of the Move and Dodge, not the "less than 1/3 HP".

B421 I only see one example, but it doesn't have any rounding at all, it uses the example of HP 10, half of which is 5, so more than HP/2 is 6 (no fractions, all whole numbers).

Not saying the conclusion is wrong, those pages just don't seem to prove the point(s).
