You can use the built-ineval()to evaluate arbitrary Python expressions from string-based or compiled-code-based input. This is a good option if you need to dynamically evaluate Python expressions. When you pass a string argument toeval(), it compiles it into bytecode and evaluates it as a...

Theround()function rounds to the nearest integer. If the decimal part is exactly 0.5, Python rounds to thenearest even number(banker’s rounding). Use math.floor() and math.ceil() To have more control over the rounding direction, you can use themathmodule: import math float_number = 7.85...
Python’s built-in round() function uses the rounding half to even strategy, which rounds numbers like 2.5 to 2 and 3.5 to 4. This method helps minimize rounding bias in datasets. To round numbers to specific decimal places, you can use the round() function with a second argument ...
In Python, there are twonumber data types:integersandfloating-point numbersor floats. Sometimes you are working on someone else’s code and will need to convert an integer to a float or vice versa, or you may find that you have been using an integer when what you really need is a float...

Rounding to 2 decimals by ceil( ) Note –This function rounds the number up, not to the nearest number Conclusion: Now that we have reached the end of this article, hope it has elaborated on the different techniques that can be used to round to 2 decimal places in Python. Here is ...
Round to 2 decimal places using the round() function 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...
TheInt()method is used to convert floats into integers, >>>b =6.9>>>int(b)6 However, you might have noticed Python doesn't return a round figure integer, it simply cuts off the decimal part. Converting Numbers to Strings A string in Python is a sequence of alphanumeric characters wrapp...
