CFAI EoC Practice Problem - Rounding error?

CFA Level III Equities
#1

Reading 23, EoC Question 2. The question is about buying futures to adjust duration.

The answer calculates to 119.69. CFAI’s solution rounds this to 119. Would you not round it to 120?

Hi, I also ran into this problem and searched Analystforum for a answer to it. So if someone have the answer, help would be appreciated. I also assumed it was rounded to 120.

edit: CFAi’s calculation show a results of 119,69 and then in the text it’s written that 119 contracts should be bought. So it’s not a normal rounding error.
