If you use floats, you will have issues with accuracy. These two fractions have identical values, the only real . 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. import math def truncate (number, digits) -> float: # Improve accuracy with floating point operations, to avoid truncate (16.4, 2) = 16.39 or truncate (-1.13, 2) = -1.12 nbDecimals = len (str (number).split ('.') [1]) if nbDecimals <= digits: return number stepper = 10.0 ** digits return math.trunc (stepper * number) / stepper Usage: Which approach is best? We have [], Table of ContentsPrefix b Before String in PythonConclusion Prefix b Before String in Python Prefix b before String denotes a byte String. round () function to print floats to a specific number of decimal points in Python The method can be best explained with an example given below: Example: b = 6.456453 #Initialising the variable "b" #using round () function to print the value till 3 decimal places print(round(b,3)) #using round () function to print the value till 4 decimal places thanks a lot. IMO timeit.timeit(stmt="round(d, 2)", setup="from decimal import Decimal, ROUND_DOWN;d=Decimal('7.325')") would be closer analog of rounding floats. In this method, the float is first converted to a string and is then worked upon. In this method, the float is first converted to a string and is then worked upon. The most common approaches to rounding a value to two decimal places are: To use the round () method.
