Hi, total uglify newbie here so apologies if this is a FAQ/obvious...

I have this declaration in a function:

const rotTol = 5;

and later this use of rotTol (and it's the only use):

if(rot < -rotTol || rot > rotTol)

what it produces is:

const n=5 .... e<-5||e>n? ....

But if I change the source to:

if(rot < -rotTol || rot > +rotTol) // note addition of unary +

the output changes to what I would expect:

e<-5||e>5?

Is this a bug or feature? I am using version 2.6.4.

Thanks.
