19 Ιαν 2009 · With Python < 3 (e.g. 2.6 or 2.7), there are two ways to do so. # Option one older_method_string = "%.9f" % numvar # Option two (note ':' before the '.9f') newer_method_string = "{:.9f}".format(numvar) But note that for Python versions above 3 (e.g. 3.2 or 3.3), option two is preferred.
You can change 2 in 2f to any number of decimal points you want to show. EDIT: From Python3.6, this translates to: >>> print(f"{1.1234:.2f}") 1.12
27 Φεβ 2023 · Format a Number to 2 Decimal Places. When working with float values containing a decimal, we sometimes want to have only one or two digits or digits as per requirements after the decimal point. So the question is how to do that? It is pretty simple by using %f formatter or str.format() with “{:.2f}” as a string and float as a number.
However, while people prefer the decimal system (base-10), computers work best in the binary system (base-2). Within the decimal system itself, you can represent some numbers using alternative notations: Decimal: 0.75; Fractional: ¾; Neither of these is better or more precise than the other.
Use the Python decimal module when you want to support fast correctly-rounded decimal floating-point arithmetic. Use the Decimal class from the decimal module to create Decimal object from strings, integers, and tuples.

Type Conversion in Python. In programming, type conversion is the process of converting one type of number into another. Operations like addition, subtraction convert integers to float implicitly (automatically), if one of the operands is float.
