Truncate to three decimals in Python

Question

How do I get 1324343032.324?

As you can see below, the following do not work:

>>1324343032.324325235 * 1000 / 1000
1324343032.3243253
>>i         


        

Answer 1

Okay, this is just another approach to solve this working on the number as a string and performing a simple slice of it. This gives you a truncated output of the number instead of a rounded one.

num = str(1324343032.324325235)
i = num.index(".")
truncated = num[:i + 4]
    
print(truncated)

Output:

'1324343032.324'

Of course then you can parse:

float(truncated)
