What type of communication is typically expressed in a decimal format?

The choice that pertains to communication typically expressed in a decimal format is money. In financial transactions, decimals are used to represent fractional amounts of currency, allowing for accurate calculations and understanding of values. For example, the price of an item might be expressed as $19.99 or $150.25, representing dollars and cents clearly through a decimal point. This decimal format is essential for clarity and precision in financial communications.

In contrast, while time can also use decimals, such as in representing parts of an hour (e.g., 1.5 hours), it is more commonly expressed in hours and minutes without a decimal. Coordinates can be expressed in decimal degrees, but they often include other notations such as degrees, minutes, and seconds. Temperature is typically presented in whole numbers or fractional form but does not require decimal formatting in the same way that financial values do.
