Rounding without using Python embedded functions

[NewCoder]

Good day,

So I am working on an assignment that calculates the position and velocity of an object at any given time. I get float(input) from the user on 3 data points as well as the time they wish to calculate to. My issue is we are assigned to truncate the calculation to 3 decimal places without using any built in functions of Python(i.e. round, print...). I have been looking for a couple days now and have not been able to find any examples of doing this manually.

if anyone could help I would greatly appreciate it. This is the last step I need to program and it is holding me up.

Thanks for your help.

you should show what you have tried.

without using any built in functions of Python(i.e. round, print...

if you can't use print, how are you supposed to display results?

Multiply, integer divide (//) by 1, true divide.

@Larz60+: If I was a prof I would say you had to name your function something particular, return the correct value, and then I would write a program to run unit tests on each program submitted.

Add one half and convert to int (whoops, int is a python function).
