New extension: Round to any number

[github-actions]

Description

This extension adds the ability to round to any number. Useful for things like a grid system.

How to use the extension

The extension is used through a function RoundToAnyNumber::RoundTo() where the first number is the number to be rounded and the second number is the number to round to.
It works based on this formula: round(Number1 / Number2) * Number2

Examples:
Rounding 12345 to 100 will give 12300.
Rounding 720 to 300 will give 600.
Rounding 7382.8129 to 0.29 will give 7 382.82 (which is a multiple of 0.29).

Thank you for submitting an extension.

What do you think about adding this expression to the rectangular grid extension?

• https://wiki.gdevelop.io/gdevelop5/extensions/snap-to-grid/

The parameters could be: "Cell size" and "Grid offset" and the expression could be used in the snap action to avoid the formula duplication.

I could add it but I have a feeling that limiting this to just that extension would feel like a bit of a waste since it is a very general tool.

Do you fear that people won't find it?
It's true that having a lot of features in one extension can make the features harder to find but the opposite is also true.
I think that these 2 features are very similar and it makes sense to have them in the same extension.

Don't get me wrong, I like the idea of integrating this into other extensions but using it for only one purpose while it's a very general tool feels limiting.

I didn't mean to hide the expression, users can still use it.
What do you mean by "only one purpose"?

Another idea is to add the expression to this extension:

This is not a common math function. I doubt people will try to search this feature in a Math extension.

Only one purpose meaning it can only be used for that extension (snap to grid) and thus limiting it to only one use - snapping

No matter the extension name, users can use the expression all the same. I don't understand your point.
What is the difference between: RoundToAnyNumber::RoundTo(123, 64) and SnapToGrid::RoundTo(123, 64)?

The question is: where someones searching for this is the most likely to search in the first place?

When i was trying to find if there was any extension for this before making it, i searched for "round" "round to any" "custom rounding" and similar.
I feel like integrating it to a math extension would be good to not make a standalone extension just for rounding.

[D8H]

Considering that there are roundTo, floorTo and ceilTo that work with power of 10 in GDevelop and a ToFixedString in the math extension to format exact decimal values, I guess people will use the new one only for writing formula around snapping (with a size and offset).
