![]() ![]() We also talked about the %d formatter which returns only a whole number from a floating point number. ![]() You use it to format floating point numbers.ĭepending on the parameters provided, the %f formatter rounds up a float value to the nearest decimal place provided. In this article, we talked about the %f formatter in Python. The %d formatter ignores the decimal numbers and returns only the whole number. When the floatNumber variable was formatted using %d, only 1 was returned. In the example above, we created a floating point number: floatNumber = 1.9876. This returns the whole number in a floating point number. How to Use the %d Formatter in PythonĪnother formatting method we can use with floating point numbers in Python is the %d formatter. You can play around with the code to see what happens as you change the number in the formatter. So %.2f means to round up to two decimal places. floatNumber = 1.9876Īs expected, the floating point number (1.9876) was rounded up to two decimal places – 1.99. The resulting value in our example is 2.0 which was returned when 1.9876 was rounded up to one decimal place. ![]() Float floatVal Float.valueOf (str).floatValue () The following is the complete example. String str '0.8' Converting the string to float. Let’s say we have the following string value. ) that comes before the digit we passed in-between % and f. To convert String to float, use the valueOf () method. Note that you'll get a similar result to the one in the first example if you omit the period/dot symbol (. This means that we want the number to be rounded up to one decimal place. Note that the %f formatter must be nested inside quotation marks, and should be separated from the floating number which it is formatting by a modulo operator (%): "%f" % floatNumber. We'll see what else we can do to modify the resulting value soon. But there's nothing too special about that. Using %f in the example above added two zeros to the number. Here's the first example: floatNumber = 1.9876 In this section, you'll see some examples on how to use the %f formatter and the various parameters it can be used with to return varying results. We can use the %f formatter to specify the number of decimal numbers to be returned when a floating point number is rounded up. The %f formatter is specifically used for formatting float values (numbers with decimals). In Python, there are various methods for formatting data types. ![]()
