The symbols, what do they mean?

[pepertje]

Okay, so I've been tinkering around with more complex scripts lately, and for that I need to know what the symbols in the prefixed boxes mean. Right now I've been able to figure out most of them:

== means "equal"

>= means "more or equal"

=< means "less or equal"

> means "more"

< means "less"

 

The only symbol I haven't figured out yet is "!=", any chance that means "does not equal"?

Hello. yes these are the common comparison operators.

 

A double equal is to define the comparison equal operator (as single equal symbol is used for assignments.)

 

the exclamation point is used to negate. So != means "Not equal to".

 

Warning about =<, it should be <=.

"!" is the notation in C++ or Java for NOT.

!false==true

so "!=" means "not equal".

I'm also pretty sure that the ! operator will work in TES scripting language. But I don't know exactly how it computates.

 

This syntax comes from C and Java languages.

There are slight differences in the different versions of TES scripting languages.

 

Papyrus for Skyrim, that includes objects, uses these automatic conversions.

 

1.0 == 1 (float cast to int)

0 == "" (zero is cast to an empty string)

0 == None (zero is cast to a null object)

false == 0 == None == "" (normal casts)

 

I think Fallout 3 has a very similar conversion system, but I am not sure.

don't forget the confusing bit where == is used in comparisons but you use just = in setting values, if you do either wron you don't get an error, it just won't work the way you want it to.
