python decimal round code example

Example 1: round to two decimal places python

>>> x = 13.949999999999999999
>>> x
13.95
>>> g = float("{0:.2f}".format(x))
>>> g
13.95
>>> x == g
True
>>> h = round(x, 2)
>>> h
13.95
>>> x == h
True

Example 2: python round to dp

round(float_num, num_of_decimals)

Example 3: round off float to 2 decimal places in python

answer = str(round(answer, 2))

Example 4: round down decimal python

import math

val = 3.14
math.floor(val) # rounds down --> 3
math.ceil(val) # rounds up val --> 4

Example 5: w=how to tell if decimal in python

i = 100
f = 1.23

print(type(i))
print(type(f))
# <class 'int'>
# <class 'float'>

Example 6: how to round to 1 decimal place in python

# Some numerical values
valueA = 3.14159265359
valueB = 1845.7409947
valueC = -100.95
valueD = 9.5432
valueE = 34.49953

# Round to different decimal places
roundA = round(valueA, 5)
roundB = round(valueB, 4)
roundC = round(valueC, 3)
roundD = round(valueD, 2)
roundE = round(valueE, 1)

# Output rounded values
print("Value:".ljust(15), "Rounded:")

print(str(valueA).ljust(15), roundA)
print(str(valueB).ljust(15), roundB)
print(str(valueC).ljust(15), roundC)
print(str(valueD).ljust(15), roundD)
print(str(valueE).ljust(15), roundE)
