Python's round() function requires two arguments. Christian Palmer. Here, we have to round off the floating-point number to 2 decimal places. This value rounded off to two decimal places. Say we want to truncate 12.3456 to 2 decimal places. print(num) // output is 343.55 my_list = [0.30000000000000004, 0.5, 0.20000000000000001] my_formatted_list = [ '%.2f' % elem for elem in my_list ] returns: The round() function returns a floating-point number which will be rounded to specified numbers, and it will round the float to two decimal places. Multiply the number by 100 and round the result down to the nearest integer. math.trunc () then truncates 1234.56 to a whole number. You can use format operator for rounding the value up to two decimal places in Python: print(format(14.4499923, '.2f')) // The output is 14.45 First is the number to be rounded. The float_value is the floating-point number n represents the total number of decimal places to be rounded in the given floating-point number. will give you an answer of 80.234 In your case, use answer = str(round(answer, 2)) We can force the number of decimal places using round (). The round () function in python rounds the float value up to n decimal places. It returns a string representing this float with two decimals. use the number_format function: echo number_format($v,2); This function is easier to use because you do not need to memorize the weird format string in printf. If you just want to print the rounded result out, you can use the f-strings introduced since Python 3.6. The syntax is the same as str.format() 1 Answer. >>> x = 13.949999999999999999 >>> x 13.95 >>> g = float(" 2021-02-04 19:01:29.

You want to round your answer. round(value,significantDigit) is the ordinary solution to do this, however this sometimes does not operate as one In floating points, 10.7 gives 10.7 as the precision value is set to 2 decimal places while in 5.5678, the value changes to 5.57. ex: tax = 34.4563 tax = round(tax, 2) #the number 2 at the end is At the 2nd decimal place is 4, and the number after it is 5. Overview of floating-point numbers in Python; Limiting float up to 2 decimal places in Python; Method 1: Using the round() function; Method 2: Using the % operator; Method 3: Using the # Rounding Down to 2 Decimal Places import math value = 1.2155 rounded = math.floor (value * 100) / 100 print (rounded) # Returns: 1.21 We multiply our number by 100 To round to two decimal places, follow the steps mentioned below:Identify the digit at the thousandths place or the third place to the right of the decimal point.If the thousandths place digit is greater than or equal to 5, the hundredths place digit will be increased by one.

This method takes as its first argument the number and the second argument is the precision after the decimal point. How to check the size of a float in python? Properties of a Python float can be requested via sys.float_info. It returns information such as max/min value, max/min exp value, etc. These properties can potentially be used to calculate the byte size of a float. I never encountered anything else than 64 bit, though, on many different architectures how to print a float with only 2 digits after decimal in python #to round floats in Python you can use the "round" function.
