python round method 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: round python

int x = 6.3456824221

#round(number_to_roundoff, round_off_till)
#round_off_till is optional

print(round(x))    		#output: 6
print(round(x, 3)) 		#output: 6.346
print(round(x, 1)  		#output: 6.3

Example 3: round python

# round(number, decimals).
# second parameter is optional, defaults to 0.

num1 = 1.56234
num2 = 1.434

print(round(num1))    	# output: 2
print(round(num2))		# output: 1
print(round(num1, 3)) 	# output: 1.562
print(round(num2, 1)  	# output: 6.3

Example 4: round python

def Round(k,b):
  if k == 0:
    return 0
  return k + b - k % b
