7.1 The Erlang Type Language. Erlang is a dynamically typed language. Still, it comes with a notation for declaring sets of Erlang terms to form a particular type. This effectively forms specific subtypes of the set of all Erlang terms. Subsequently, these types can be used to specify types of record fields and also the argument and return

An IP datagram header is of variable length. This length is measured in the number of 32-bit words and is given in the segment corresponding to HLen. The minimum value of HLen is 5. Tag must be an atom, while Value must be a literal term.

{\displaystyle \lambda /k.} Tag must be an atom, while Value must be a literal term. As a convenience in user-defined attributes, if the literal term Value has the syntax Name/Arity (where Name is an atom and Arity a positive integer), the term Name/Arity is translated to {Name,Arity}. It supports internel types (defined in module), external (exported in other module) and inline types (defined in string). At the moment it does not support types in variables like: sheriff:check(Val, Type) but we are working on it) Dialyzer is a very effective tool when it comes to analyzing Erlang code.

Syntax Is_Integer(X) Parameters. X - A number value. Return Value. The return value is true if the number specified as a parameter is a Integer value, else will return false. The Erlang distribution is the distribution of the sum of k independent and identically distributed random variables, each having an exponential distribution. The long-run rate at which events occur is the reciprocal of the expectation of X , {\displaystyle X,} that is, λ / k .
