im a Beginner in python and i don’t know how to Write a program that reads a number from the input and prints the next multiple of 10 that is greater than this number. For example, if the number 11 is read from the input, the number 20 should be printed. If the number 40 is read, the number 50 should be printed.

Please show the code you have written so far so that we have something to work from.

Cut-n-paste your code between so-called code-fences like this:

```
```
print('Your code here')
```
```

I assume that when you say “greater” it means strictly greater. For example, that for the input `10`

the result should be `20`

. Maybe clarify if for the input `10`

the output should be `10`

.

You know that the floor function \lfloor\cdot\rfloor satisfies (perhaps that’s you definition)

\lfloor y\rfloor \leq y<\lfloor y\rfloor

So, putting y=x and multiplying by 10

10\lfloor\frac{x}{10}\rfloor\leq x<10\lfloor x/10\rfloor +10

So, the smallest multiple of 10 larger than x is 10\lfloor x/10\rfloor +10.

Check in the documentation if the function `math.floor`

gives the same result as \lfloor\cdot \rfloor and then you could do `10 * math.floor(x/10) + 10`

Check which type of input you will get. Can `x`

be any of the values of `float`

? Maybe cover the cases `x`

equal to the values `float('inf')`

, `float('-inf')`

, `float('nan')`

.

Some things to consider:

- user input is string, so conversion to int is required
- there is // (floor division) operator

For example:

```
>>> int('11') // 10
1
>>> (int('11') // 10 + 1) * 10
20
```

For an int calculation I would not be using math.floor

The modulus operator % and the integer divide // are, I think, the key to this.

As you say need to confirm if input of 10 is expected to be 20 or 10.

thank you for help
