Location of table describing multiple equal-sign operators

[WeThotUWasAToad]

Hello,

For a description of what the other operators do, see their related entries in this table.

The above statement regarding a bunch of equal-sign operators (:= += -= *= /= //= .= |= &= ^= >>= <<=) is from the AHK docs (https://autohotkey.com/docs/Variables.htm#Operators) in the section located here:

AHK docs > Variables & Expressions > Operators > Expression Operators (in descending precedence order) > Assign

Should the table referenced in the quote have a hyperlink? If not, where is the table with descriptions located?

Also, what is the function of the operator -= (which is the topic I was looking up in the first place)?

Thanks

-= subtract something from a variable.

Code: Select all

var := 10
var -= 5
MsgBox, % var

Is the table not the one on the page in the docs ?

Can't help you with all that, but I can help you with "-="

Total <------------------------ Variable

Total:= 20 <-----------------------Total now has a value

Lets add to total

Total := Total + 10 <--------------- Total now has a value of 30 but look how much we had to type

Lets do the same thing short hand

Total:= 20
Total+=10 <-------------Just like before we added 10 to the value of total

Now we subtract

Long way:
Total:= 20
Total:=Total-10 <----------------------- Total now has a value of 10

Short way:
Total:=20
Total-=10 <----------------------- Total now has a value of 10

if we only need to add or subtract 1 we can do it like this
Total++ <---------------------------- added 1 to total

Total-- <------------------------------- subtracted 1 from total

Hope that was clear.

Thanks for the responses.

Yes, it actually is. I just checked it again and realized the prefixes (to each of those multiple operators) are listed elsewhere on the same page (i.e. without the accompanying equal sign).

Yes, that is extremely clear — and quite simple (as are most things once you understand them).

Thanks
