How should the amount $237.54 be transmitted over radio?

The correct method for transmitting the amount of $237.54 over radio is to say "Two three seven decimal five four." This approach follows standard radio communication protocols, which emphasize clarity and precision, especially when conveying numerical information.

Using "decimal" clearly indicates the separation between the whole number and the fractional part, helping to avoid any potential misunderstanding. This format is particularly important in maritime communication, where miscommunication could lead to significant operational errors.

While alternatives like saying "point" or variations of written numerals might seem viable, they can lead to confusion, especially if the receiver misinterprets a phonetic sound or has difficulty hearing in noisy conditions. By explicitly stating "decimal," the speaker effectively reduces the risk of error in the transmission, ensuring that the figure is understood as intended.
