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.
This C tutorial explains how to declare and use floating-point (float) variables with syntax and examples.
May 3, 2019 · By definition, float in C, C++ and C# is a variable with floating decimal point. It can contain whole numbers as well as fractions.

a Python float is a numerical data type that represents a floating-point number. A floating-point number is a number with a decimal point or exponent notation, indicating that a number is a certain number of digits before and after the decimal point or exponent. For example, the number 1.23 is a floating-point number with one digit before the decim...
There are multiple ways to create floating-point numbers in Python. Most of the time, you will simply enter the number as-is: But you may want to convert a number or a string to a float using the float() function. The variable f will become 2.0 in all cases below: You can also use scientific notation:
Working with floats is not much different from working with integers. You can do the usual addition, subtraction, multiplication, and division.
Let’s do a little experiment. For extra dramatic effect, try this for yourself first: Did you expect the output to be 0.3 like any normal person would? I don’t blame you, but you’re wrong! The output is actually 0.30000000000000004. As absurd as this might seem, there’s an explanation. First of all, some fractional numbers are endless. E.g., when y...
You can convert a float to other data types, such as int or str, using the built-in functions int() and str(). For example, the following code converts the float 1.23to an integer and a string:
Aug 14, 2020 · Techopedia Explains Float. Since the early days of computer programming, floats have provided the ability to hold numbers including decimal fractions as data types. Understanding the nature of the float is vital in type conversion, in declaring variables, and in using variables within a codebase.
Here are some definitions of floating point variables: float fValue; double dValue; long double ldValue; When using floating point literals, always include at least one decimal place (even if the decimal is 0).
