how to round down and round up the decimal vlaues in pytho.

user input

      a =2.336  After round up it should be like a =2.34
      a =4.13623  After round up it should be like a =4.14

Is there any built in functions in python to manipulate

CodePudding user response：

you could try something like a = 2.336 a = math.ceil(a*pow(10,2))/pow(10,2)

here 2 stands for the precision you need behind the floating point

CodePudding user response：

You can use the ceil() and floor() functions from the math module. Here's some code to help you get started.

def round_up(n, decimals=0):
   multiplier = 10 ** decimals
   return math.ceil(n * multiplier) / multiplier
