Converting Decimal to Text: Know Your Numbers Better

As human beings, we are wired to express ourselves in words. Words are what we use to communicate with each other, express our thoughts, and make sense of our world. However, in the field of programming, numbers play a key role in expressing complex ideas and concepts. While decimal numbers are common to many, knowing how to convert them to text is essential for those building computer programs. In this blog post, we will explore the process of converting decimal numbers to text and how it can be helpful in your programming journey.

 

Decimal numbers are used in everyday life, ranging from prices to measurements. These numbers can be expressed as fractional or non-fractional numbers and can be converted into words using simple rules. For example, 45.68 can be expressed as "forty-five point sixty-eight". The first step in converting decimal numbers to text is understanding the decimal point. In the example above, the decimal point separates the whole number (45) from the decimal (0.68). To express the whole number, we use the rules followed in writing numbers in words. For the fractional part, we use the rules of writing a decimal in words.

When writing decimals in words, we use place value to determine the name of the number. Just like in whole numbers, each place value has its own name. For example, in the number 45.68, we use the names tens and hundredths to express the numbers 4 and 6 respectively. The whole number (45) is expressed as forty-five, while the fractional part (0.68) is expressed as sixty-eight hundredths. Suppose we have a decimal value of 871.341, we can write it as "eight hundred seventy-one point three four one".

The process of converting decimal values to text becomes a little more complicated when we are dealing with larger numbers. In such cases, we resort to using the scientific notation. Scientific notation is the recommended method for writing large numbers as it helps to keep the numbers neat, organized, and readable. For example, a value such as 72456134.000056 can be written as "7.24 x 10^7", where 7.24 is the number in front of the decimal point, and 7 is the power of 10. When expressing decimal numbers in this form, we follow the same rules as that followed for smaller numbers.

There are programming languages where there are functions that can be used to convert decimal values to text. For example, in Python, there is a function, "num2words" in the "num2words" library which can be used to convert decimal numbers to text. Also, Visual Basic supports the "FormatCurrency" function that formats the output as currency. These functions remove the need to write complex algorithms for converting decimal numbers to text.

 

Converting decimal numbers to text is an essential skill for any programmer who works with numerical data. Knowing how to express decimal numbers in words is useful for financial applications, technical documentation, and other fields where numerical data is present. Understanding place value, scientific notation and built-in functions can save time and increase efficiency. In conclusion, having a basic understanding of the conversion of decimal numbers to text is essential for programmers who want to create strong, cohesive, and coherent programs.
