I need to convert the values ​​in the string to numeric values. I found this very difficult. Do you have any quick methods?

I found that converting them requires a complicated process:
e.g. ["6.9","232","-8.3"]

You can just calculate with them?
In AHK every string can be used like a number as long as it only consists of a single number (e.g. the numbers you presented.)

There are two (suitable) functions available, integer and float.

Yes, but as some DLL parameters, need to convert.

Can you link the addresses of these two functions? I can't find.

thank you very much. My "help document" is too old.

One problem is that its conversion is not accurate, it is very bad when converting JSON data:

Float("6.9") ;==>6.9000000000000004

You might be interested in this topic.

this topic, in addition to explaining why "Float()" cannot be accurately converted, is there any help for "accurate conversion type"?

AutoHotkeys floating point numbers are as precise as a double sized float (its the standar size).
If you want more precision you need a different type.

The conversion is accurate. The data type is not (for decimal fractions). You can't even choose to use or simulate a different data type if you're using DllCall. At some point the value must be converted to the type that the external function requires.
