Why does my BA II Plus look like it is rounding CFA answers to whole numbers?

The likely issue is the display setting, not the underlying calculation. If the calculator is set to show zero decimals, a value such as 1,023.68 may appear as 1,024.

For CFA work, that can be dangerous because many calculations need more precision until the final answer. Set the display to show enough decimals for TVM, fixed-income, and statistics work, then round only when the question asks for a final format.

The important exam distinction is this: the displayed number may be rounded, but your reasoning should still track the more precise value.
