What character structure can FixedDecimal hold?

FixedDecimal is designed to accommodate both whole numbers and decimal numbers. This character structure provides the flexibility needed for various applications where monetary values or measurements with precision are essential. By allowing for both types of numbers, FixedDecimal can effectively represent values like 10 (whole number) and 10.5 (decimal number) without losing precision, making it particularly useful in data analysis and calculations that require accuracy.

In contrast, the other options limit the capabilities of FixedDecimal. Whole numbers only would exclude any need for representation of fractions or decimals, which is a significant limitation. Decimal numbers only would fail to accommodate scenarios where pure integers are needed. Lastly, the representation of only characters and strings would not align with the numeric functionalities that FixedDecimal is intended to provide. Thus, recognizing that FixedDecimal encompasses both whole and decimal numbers helps in understanding its broader application in data processing.
