Hi Koewn - A caster with a Divine Value 3 gets no spells at 1st level, because 1.33 x 0 = 0.
A caster with Divine Value of 4 would also get no spells at 1st level, except for a rule in the text. I've bolded the relevant text below:
Divine 4: A Divine Value of 4 gives the class the ability to turn undead and cast spells as a cleric, with additional bonus spells per level. Increase the class’s spells per level by 50% to determine the class’s spell progression. Round fractions of .5 or greater up. The class uses its class level for all level-dependent spell ranges, durations, and damages; these are not increased by 50%. In addition, a class with Divine 4 can cast one 1st level divine spell per day at 1st level. The class’s divine spell repertoire is based on a spell list of 15 spells per level.
