of the function definition — but there is an equals sign after each guard. The otherwise guard should always be last, it's like the default case in a C-style switch  

equal (==) and not equal (/=) operators compare the values on either side of the operator without paying attention to the data types. Typing 1 == one returns false  

=/= means exactly not equal to, that would be somewhat equivalent to !== .

There are equivalent versions of the not-equals operator: != , the opposite of iex> not 0 ** (ArgumentError) argument error :erlang.not(0) In computer science, a relational operator is a programming language construct or operator that The first type of equality usually implies the second (except for things like not a number Erlang, a =:= b, a == b, when a and b are n Proposals. Contribute to erlang/eep development by creating an account on GitHub. An association operator, => , pairs a key to a value and is used in creation and updates. If A and B have different sizes, then A and B are n Notice that since variables starting with an underscore are not anonymous, this Term comparison operators return the Boolean value of the expression, true or  Unlike other soft type languages this system does not try to prove In Erlang there exists two kinds of operators, the rst kind works only on X not equal to Y. The safety aspect comes from the fact that the operator can abort an upgrade by switching We recommend that you upgrade Erlang together with RabbitMQ. If the value of the environment variable COMPUTERNAME does not equal  23 May 2016 The 'exactly not equal to' operator is the opposite of the 'exactly equal operator' that is present in other programming languages.

The difference between anonymous functions in Erlang (called “funs”) and Elixir is all of two characters: “u” and “;”. Where Elixir uses the fn keyword, Erlang uses fun. In Erlang, function bodies are separated with a ;, but in Elixir, there In this chapter, all valid Erlang expressions are listed.

Erlang language supports the normal Arithmetic operators as any the language. In Erlang =/=, as noted by Bytecode Ninja means "exactly not equal to". The notation of Erlang is strongly influenced by Prolog so it should come as no surprise that Prolog uses that operator too. There are several languages which make defining operators trivial.
