Excel is at least capable of basic floating-point arithmetic. From the paper:

As mentioned in Section 3, we round all real numbers to their nearest integer values, based on the assumption that GPT-4 might have difficulty handling real numbers directly. In this section, we perform an ablation study to validate this assumption. The results are presented in Table 5, which demonstrates that using rounded real numbers can indeed enhance the performance of GPT-4, thereby confirming our hypothesis.
