According to the Contacts section:
Contacts that hate you are half cost.
Affiliations give “free” contacts. Work-mates, partners, friends, former subordinates and so on. Take the cost paid for the affiliation and divide it in half.
But in a section immediately after:
Lastly, an affiliation earns the character discounted goods or services—a one-time resource point bonus to be spent in character generation. This represents the perks afforded to the organization’s members. Divide the affiliation cost by 5 (round down) for the resources point bonus.
Since it specifies 'round down' here, what was the default before? Round up? Also round down? Or potentially having a half-point?
