Guards may appear as part of a function definition or in "receive", 'if', "case", and " try/catch" expressions. We can use a guard in a function definition. Example 

f() -> {ok,[A,B]}=io:fread("","~d~d"), T = case 9>B rem 110 of true->B div 100;  Erlang is a concurrent functional language based on the actor modelof concurrency. In the purest form of this model, actors are realizedby processes that do not  Avhandling: Model-Based Protocol Testing in an Erlang Environment.

The Erlang distribution is used to model the time in between incoming calls at a call center along with the expected number of calls. This allows call centers to know what their staffing capacity should be during different times of the day so they can handle the incoming calls in a timely fashion without losing money by staffing too many employees during a given shift. 12 Dependencies between Test Cases and Suites 12.1 General. When creating test suites, it is strongly recommended to not create dependencies between test cases, i.e. letting test cases depend on the result of previous test cases.

In Erlang, the `if` is an expression which can have multiple branches. The branches are scanned sequentially Next: Case of → Erlang by Example A case in Core Erlang must not fall off at the end, that is, there must always be a clause that will match. In this example, the last clause with a variable pattern and a true guard is guaranteed to match.

[citation needed] In Erlang's analysis of efficient telephone line usage he derived the formulae for two important cases, Erlang-B and Erlang-C, which became foundational results in teletraffic engineering and queueing theory. His results, which are still used today, relate quality of service to the number of available servers. It is a derivation of the Poisson Formula – but using a special case where k=0. This assumes that the Average Handling Time of calls is distributed by a version of Poisson called the Erlang Distribution .
