Final answer:
The Fixed format displays numbers with at least one digit after the decimal point and considers trailing zeros to be significant. This format is distinct from scientific notation, which represents numbers as a coefficient times a power of ten.
Step-by-step explanation:
The format that displays at least one digit after the decimal point is known as the Fixed format. The Fixed format ensures that numbers are displayed with a specific number of decimal places, making trailing zeros after the decimal point significant. For example, if you have the number 25.0 in Fixed format, it indicates that a precise measurement was made to the tenths place, and the zero after the decimal is significant. In contrast, Scientific notation presents numbers as a coefficient (all digits are significant, including zeros) times a power of ten, which simplifies understanding and working with very large or very small numbers. For instance, the number 12,700,000 would be written as 1.27 x 10· in scientific notation.
