The Python decimal module provides support for fast correctly-rounded decimal floating point arithmetic. By default, Python interprets any number that includes a decimal point as a double precision floating point number. TheDecimalis a floating decimal point type which has more precision and a smalle...
The round() function is Python’s built-in function for rounding float point numbers to the specified number of decimal places. You can specify the number of decimal places to round by providing a value in the second argument. The example below prints 34.15. # Example number to be rounded ...
