const

The const modifier is used to create a constant.

Syntax

The syntax of const modifier is as follows:

 const <type> name = <initializer>

The <type> here must be predefined type in Cyclone, and the <initializer> could be a value or an expression that evaluates to a value.

Scope

The const modifier must appear in front of a type declaration.

Semantics

A constant is always compiled into a pre-defined value and cannot be re-assigned (changed). A constant cannot be used with fresh or initial expressions.

An Example

  const real PI=3.14;
