Jan 3, 2016 · You need to make one of the inputs a floating point value. Try changing 2 to 2.0. E.g.: >>> x=10 >>> x**2 100 >>> x**2.0 100.0 Note that in Python 3 division automatically returns a floating point, and the new // operator explicitly does integer division.

Jan 9, 2024 · Learn all you need to know about Python floats: how to create them, how to convert from and to other types, and some important limitations.

Python has the following data types built-in by default, in these categories: You can get the data type of any object by using the type() function: Print the data type of the variable x: In Python, the data type is set when you assign a value to a variable: If you want to specify the data type, you can use the following constructor functions:

Feb 21, 2025 · A float (floating-point number) is a data type used to represent real numbers with a fractional component. It is commonly used to store decimal values and perform mathematical calculations that require precision.

Mar 19, 2025 · Directly assign a float to a variable. Calculate a float through other variables. Convert an integer to a float with float (). Convert a string to a float with float ().

This page is a summary of Python float (floating-point number or decimal number) data type – its basic characteristics, how to create a float variable, how to convert other data types to float, and basic arithmetic and comparison operations.

To declare a float data type in Python, you simply assign a decimal value to a variable. This can be done directly or through a function that returns a float. Here are some examples: Understanding the key features of floats will help you utilize them effectively in your code. Immutability: Once you create a float, you cannot change its value.

In Python, a float (short for floating-point number) is a numeric data type that represents real numbers with a decimal point. Unlike integers, which handle whole numbers, floats accommodate fractional values, making them ideal for approximations of continuous quantities.

In this tutorial, you'll learn about the Python float type, how Python represents the floating-point numbers, and how to test the floating-point number for equality.

You can create floats using literals, the float() constructor, or by converting strings or other numeric types: A numeric value (integer or float) that will be converted to a float. A string representing a float. This is a required argument. Creating a zero instance of a float: Creating floats using literals, including scientific notation:
