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

Maybe this way:

def myTrunc(theNumber, theDigits):

    myDigits = 10 ** theDigits
    return (int(theNumber * myDigits) / myDigits)
