@Domhell

I try to make it possilble to round a number that is not a comma 😊 problem…

but taking the first number, with extra a nummeric 0 is not possible

BUT I found ‘round down’  
BUT IS THIS ONLY FOR COMMA NUMBERS?

Please who can help me: because teacher in school only first let children do maths with the T (first number with zero) and than the rest…

@karelrosseel82 I’ve moved this question to its own topic since it specifically concerns using the `round` block.

The first question in your screen shot asks:

**"is round down only for numbers like 3.1 i.e. decimal numbers"**

Yes, all 3 of these options expect a comma number (decimal number) and return an appropriate whole number (integer).

![rounding](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/5/5/554d43db6f16bebbd85024365dac12f425f3acc4.png)

To test a block like this for yourself you can create a new test project and do something like this:  
 ![testing](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/2/3/2353b9974166ae9efa2102f60ef3096ba364a6e1.png)

If you now preview this in Thunkable Live you can try out different combinations of number and rounding for yourself.

For example:

- round(6.1) = 6
- round(6.8) = 7
- round\_up(6.1) = 7
- round\_up(6.8) = 7
- round\_down(6.1) = 6
- round\_down(6.8) = 6

* * *

Your second question then, is something like:

**"Can I disregard the ones value of a number, i.e round down to the nearest tens value?**

Again, this is pretty straightforward if you break it down into smaller pieces.

- The first thing is to divide your number by 10, thus 61 becomes 6.1, 68 would become 6.8
- Next, round down the result of this calculation so 6.1 becomes 6 and 6.8 also becomes 6  
\*Finally, multiply the answer by 10 to get 60

Hope that helps.
