Question

How can I render decimal numbers in Python? For example, in the number 3.14373873 only up to and including the number 4.

I want to round the decimal numbers from a specific place:

As example:

3.14373873 -> 3.14

Answer 1

you can use the round() function:

Example:

p = round(50.12345,3)
print(p)

Output:

 50.123

Example 2:

# for integers
print(round(15))

# for floating point
print(round(51.6))
print(round(51.5))
print(round(51.4))

Output:

15  
52  
52  
51
