It was supposed to say 0.5 / 0 since its 1/2 a stat (forgot which one) that is 1 for me.
I know the system rounds down on most of these values, but it would be weird if someone could not even jump half a meter.
Besides, the core-book did not say I should round down, so I didn't ;)

EDIT: wrote it down slightly different, hopefully it makes more sense now ;)
Let me know if i should not have done it like that though.
