why 25 * 1.3 gives 25 in construct?

doing this code

where Stats.At(Hardness,1) equal to 1.3

which is shown in the print console

but the result as you can see is equal to 25 instead of 32.5 which is right value of 25 * 1.3

is it bug or feature of construct?

It's not a bug, this is how strings are concatenated. Add round brackets:

... & "/" & (25*Stats.at(Hardness,1))

... & "/" & (25*Stats.at(Hardness,1))

added, nothing changed

also, we can't use int in this case, because 1.3 will be rounded to 1, is it always like this? I never had such a problems

Ok, I can use float() to convert this array value into a number, and the calculation becomes right

but the strange thing, in another block Stats.at(Hardness,1) this value working as expected without float or anything

as for me, it is not right when this basic things working different in the different places

Maybe the value is stored as string in the array? You can test this by printing Stats.AsJSON to console log. If the value is shown as "1.3", then it's a string.

Yes, it is a string, but I'm wonder why I didn't experienced this situation before, in previous years

Anyhow, I will always use float() now, to avoid this situations

To be clear the issue is from multiplying a number by text.

Usually construct lets you know that it can’t do that when you write

25*”1.3”

So since the value is in an array it doesn’t know if it’s a number or text till runtime. And construct doesn’t really ever give runtime errors. So it just silently doesn’t do anything when trying to multiply a number by text.
