Rounding For Duration/Damage Question

Does Guildwars follow the usual rounding format? i.e. 0.5 rounds up? For example with 9 in Illusion, the duration of Conjure Phantasm is calculated to be 9.5 seconds, would Guildwars just round the duration up to 10 seconds then?

Thanks for any help that I can get on this topic.

AFAIK the numbers are rounded for display only, and not for the calculations.

thanks, this helps out a lot, it still seems a little strange that while it displays 10 sec, the spell would only last for 9.5 sec. So if there was to be lets say, 2.5 pips of health degeneration (for a spell like life siphon), it would say three, but only actually take health at 2.5? just wanted to know if the situation would apply to health/energy degeneration. thanks.

HP an energy pips are whole numbers only, you can have either 2 or 3, and not 2,5.

thanks for the clarification
