21 lip 2017 · There are two methods: float_number = float(decimal_number) float_number = decimal_number * 1.0. First one using the built in function and second one without any function, but take care about the 1.0 not 1 as it should be float so the result will be float. edited Nov 3, 2023 at 22:04.

25 lis 2008 · Python does support Decimal creation from a float. You just cast it as a string first. But the precision loss doesn't occur with string conversion. The float you are converting doesn't have that kind of precision in the first place. (Otherwise you wouldn't need Decimal)
22 mar 2024 · Learn how to use the float() function to convert decimal numbers to floating-point numbers in Python. Understand the differences and use cases of decimal and float data types, and how to handle them together.
1 dzień temu · The decimal module provides support for fast and accurate decimal floating point arithmetic. It offers advantages over the float datatype, such as exact representation, significant places, and user control over rounding and signals.
20 sie 2021 · Learn how to convert integers to floats and vice versa using built-in functions, and how to convert numbers to strings and vice versa using str() method. Also, see how Python 3 handles division and decimal places differently from Python 2.
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.
9 sty 2024 · Use the decimal module: The decimal module in the Python standard library provides support for decimal floating-point arithmetic. This allows you to work with decimal numbers that have fixed precision, which can be useful for applications that require more precise calculations than what is possible with regular floats.
