Explore how to convert numeric Uber ride fares into their English word equivalents for improved accessibility. Understand the process of dividing large numbers into sections like billions, millions, and thousands, then transform these into readable words. This lesson helps you implement a method to handle large integers efficiently and prepare the output for text-to-speech applications.
We'll cover the following...
Description
At the end of a ride, the Uber app displays the fare to the customer. For accessibility, we want the fare to be read out, should the customer so choose. Assuming that the ride fare is an integer and that a text to speech engine is available, all we need to do is to convert the fare to English words.
