A textual number converter is a tool that transforms numeric values into their written or textual equivalents. For example, the number 123 is converted to "one hundred twenty-three". This is particularly useful in applications where numbers need to be presented in a human-readable format, such as in legal documents, invoices, or automated customer communications.
Textual number converters typically follow a systematic approach to break down a number into its constituent parts (units, tens, hundreds, etc.) and then map each part to its corresponding word. Below is a simplified breakdown of the process:
| Number | Textual Representation |
|---|---|
| 7 | Seven |
| 42 | Forty-two |
| 105 | One hundred five |
Textual number converters are widely used in financial systems (e.g., writing checks), educational tools, and accessibility applications to ensure clarity. They help reduce ambiguity and make numeric content more accessible to users who prefer or require written descriptions of numbers.
Creating a textual number converter involves writing a script or program that handles different number ranges and language rules. For instance, English converters must account for unique number names (e.g., "eleven" instead of "ten-one"). Below is a high-level approach:
