Basics
Crystal Operators
Crystal Operators
Crystal operators include arithmetic and logical with type safety.
Introduction to Crystal Operators
Crystal language provides a variety of operators for performing operations on variables and values. Crystal operators are type-safe, meaning that they ensure operations are performed on compatible types, reducing runtime errors.
Arithmetic Operators
Arithmetic operators in Crystal are used to perform basic mathematical operations such as addition, subtraction, multiplication, and division. These operators work similarly to other programming languages.
Logical Operators
Logical operators are used to perform logical operations and return a Boolean value. They are often used in control flow statements.
Comparison Operators
Comparison operators are used to compare two values. They return a Boolean value indicating the result of the comparison.
Type Safety in Crystal Operators
Crystal enforces type safety by ensuring that operations are performed only on compatible types. This reduces runtime errors and enhances code reliability. For example, trying to add a number to a string will result in a compile-time error.
Conclusion
Understanding operators in Crystal is fundamental to performing operations efficiently and safely. By leveraging type safety and knowing the various operator types, developers can write robust Crystal code.
