In Erlang, the condition is an expression which evaluates to either true or false. If the condition is true, then statement#1 will be executed else statement#2 will be executed.
第一個決策聲明中，我們來看看 'if' 語句。在 Erlang 這個語句的一般形式，如下面的程序所顯示 -if condition -> statement#1; true -> statement #2 end. 在 Erlang 中，條件它是計算結果爲真或假的表達式。如果條件爲真，則 statement#1 將被執行，否則 statement#2 將被執行。
2007 — My older PDF version is hereby deprecated, so if you have any links please update Erlang skulle kännas som ett nederlag (några av er kanske förstår varför). Anyway, trying to figure out a good opening statement for this Everything else is out of the band and part of its "app" experience. I'm looking to see if there's information or opinion about the differentiation between 9 apr.

While the Erlang B formula isn’t really used within contact centre today, both Erlang C and Erlang A still have a huge part to play in contact centre workforce management (WFM). Logical errors are the hardest kind of errors to find and debug. They're most likely errors coming from the programmer: branches of conditional statements such as 'if's and 'case's that don't consider all the cases, mixing up a multiplication for a division, etc. Erlang (/ ˈ ɜːr l æ ŋ / UR-lang) is a general-purpose, concurrent, functional programming language, and a garbage-collected runtime system.The term Erlang is used interchangeably with Erlang/OTP, or Open Telecom Platform (OTP), which consists of the Erlang runtime system, several ready-to-use components (OTP) mainly written in Erlang, and a set of design principles for Erlang programs. Not to refute your experience, but "adding true -> ok to every if statement" sounds like an anti-pattern. A couple of notes to elaborate: 1. If-statementes should rarely be used in Erlang because case is preferred
And about return in general -- in Erlang (and other functional languages) program is composed of expressions that get evaluated to values, there are no statements.

For reliability reasons every statement in erlang must have some return value. In this code your if statement has no return value when X and Y both are nonzero. So your code should change to this: test(X, Y) -> if X == 0 -> -1; Y == 0 -> -2; Comments within Erlang code shall start with one percent character (%).
