Convert string to number

[Deadfast]

Hello guys,
I've been struggling to get my dialog to work.

I have a field in which you enter a value and after pressing a button the value is transferred further.


Well, the problem is it's a string and I need a number.



I've searched both this and the BI forum and found this:

Unfortunately it either doesn't work with SQF or I don't know how to use it properly.




Thanks for your help,
Deadfast

Doesn't need to be that complicated in the wonderful world of ArmA anymore. Now you can simply use call compile:

Code: [Select]

_numberString = "string";
_number = call compile (_numberString);
And you should have yourself a nice little proper number. Good luck!

Ah great, thank you!


I'll try it out ASAP

Er, no. If you do it that way, you allow the player to run arbitrary scripts, which even if they are not maliciously doing it might well cause accidental damage (Not too critical in SP, but a definite no-no in MP).

You could just use the command parseNumber though, since well, that does exactly what you need! Be wary that anything that doesn't parse to a number, such as "Frogtree" will give you 0 and strings that contain numbers and non-numbers will give those numbers ("7 - fish" gives 7). Shouldn't be a problem though.

Holy cow! Didn't even know there existed such a thing :O One learns new things every day...

Yes: use Spooner's way.
