As I've said before, there are three types of numbers: the positive, the zero, and the negative ones. Today, we shall pay attention only to the negative ones now. Make a loop that will accept random decimal/float numbers. When the user inputs 0, the loop will terminate and then output the sum of all negative numbers inputted in 3 decimal places.
Let's code this.
Input
Multiple lines containing a decimal .
2.4434
-1.3433
-2.444
6.432
0
Output
A line containing a decimal with three decimal places.
-3.787
negativeSum = 0
number=1
while number!=0:
number = float(input())
if number< 0:
negativeSum += number
print("{0:.3f}".format(negativeSum))
