Digits after the decimal point

It’s also possible to convert floating-point variables to integers by removing everything that comes after the decimal point. To do that we can write:

num = 43243.6350207935
res = int(num)
print(res, num)

This program would print 43243 43243.6350207935. So, the res is an integer, while num is a floating-point value.

Challenge

Given a floating-point number, remove the digits before the decimal point.
