How to get round values

Question

I have tried paint cost challenge in code coach
But i am getting errors as my output is like 55.0
and expected output is 55

color=int(input())
supplies=40
cost=supplies+(color*5)
total=((10/100)*cost)+cost
print(total)

Answer 1

Use math.ceil or add just 0.5 in total and cast with int

print(int(math.ceil(total)))

Or

print (int(total + 0.5))

Answer 2

Guraja Teja Surya Lokesh Kumar

Do this

print(int(total))

Answer 3

I Am AJ ! ; The result is correct for certain numbers, but not for all:

print(ceil((canv_brush +(colors * onecolor)) / 100 * 110))
print(int(((canv_brush +(colors * onecolor)) / 100 * 110)+0.5))

# when giving input = 14 (or 15,...)
# result with ceil(N) = 122
# result with int(N +0.5) = 121

Answer 4

Guraja Teja Surya Lokesh Kumar It says to "round up", so use math.ceil(total)

and don't forget to import math library.

Answer 5

I Am AJ ! , you mentioned to use something like that: " ... or add just 0.5 in total and cast with int"

- > but this does not give the same result than using ceil()
▪︎assuming we have a value of 2.3 and try to round this UP:
▪︎math.ceil(2.3) = 3
▪︎2.3 + 0.5 = 2.8, int(2.8) = 2

Answer 6

Just use print( int(total)) for interger

Answer 7

There might be possibility of all test cases output is like

5.6
5.7
5.8
5.9
4.5

So if we use ceil or just add 0.5 and cast with int. In both cases output will be same.

Answer 8

int(math.ceil(cost+(10*cost/100)))

Answer 9

Lothar

I have solved in that way and passed all test cases.

Answer 10

Atul

Well I don't know but I have passed all test cases 😀🤣

Answer 11

Lothar

I think I also know whatever you want to say but fact is problem solved in that way. So I answered here. I will not give wrong solution.

Answer 12

I Am AJ ! now its passig 3 test cases and 2 test cases failed.And those two are hidden test cases

Answer 13

Use this line

Answer 14

I Am AJ ! I think so the difference in all cases are less than 0.5 . Correct me if I am incorrect

Answer 15

I Am AJ ! Yes because in all cases it will return int. So it's correct

Answer 16

Hey buddy, if you notice that game happens in (10/100)'s part of code where 0.1 will be multiplied by your cost then cost added and it will be total ....
Now total is in float value ...
And you need to convert it into int
Print(int(total))....
I hope it will help you and better your understanding to find an error by your self.

Answer 17

#i would rewrite your code and do it this way

x = int(input())
colours = 5.00*x
canvas_and_brushes = 40.00
tax = (colours + canvas_and_brushes)/10
total_cost = colours + canvas_and_brushes
print round(total_cost + tax)
#that should work, get back to me if im wrong
