Actionscript

In Actionscript, what would this mean:

if (-1(-1(eval("someVariable"))) == eval("someVariable"))

Particularly the nested -1s. What do those do?

A barrel roll

I came.

This means several things:
You're not in /prog/.
You're actually in /tech/.
Actionscript is not a technology, please update your biocache.
[spoiler][code]if (the negative of (the negative of (evaluate what "someVariable" means))) is equal to (evaluating what "someVariable" means)) then do whatever[/spoiler]
Google it and stop wasting threadspace.

if (-1(-1(eval("someVariable"))) == eval("someVariable"))

getting the value of some variable*-1 and then that * -1 and then testing it against the same variable.

You're going to get True every time because you're basically testing the same variable against itself, it's always going to be true

-1 is not a function

-1 is not a function

No, it's your IQ. Two posters already explained that it's, well, uh... -1. A number which, if used for multiplication, only changes the sign, not the unsigned value of any other number, thus being ideal to turn something positive into its negative equivalent - or vice versa, should the original value already be negative.

And as #8 rightly said, negating something twice returns the original value, thus making the whole operation pointless.

The 1s are unnecessary -
-(var) == -1*(var) != (-1(var) => error: `1': unknown function)
Thanks for explaining basic maths for me though, I'd almost forgotten.
