![]() checks whether the two values are equal, if equal returns true, if not return false The following table lists the commonly used relational operators in Lua language, setting the value of a to 10 and the value of b to 20: OperatorĮqual to. Print ( "value of Line 7 - c is ", c ) -Print result: -value of Line 1 - c is 31 -value of Line 2 - c is 11 -value of Line 3 - c is 210 -value of Line 4 - c is 2.1 -value of Line 5 - c is 1 -value of Line 6 - c is 441 -value of Line 7 - c is -21 relational operator Represents a separate line of execution used to execute a coroutineĬ = a ^ 2 print ( "value of Line 6 - c is ", c ) Represents any C data structure stored in a variable # Lua Data Type Data NameĪn invalid value(The equivalent of false in a conditional expression)īoolean value containing two values: false and trueĪ real number, representing a real floating point number of type double, or an integerĪ string, represented by a pair of single or double quotesĪ data structure of Lua, used to create different data types, such as arrays, dictionaries, and etc In other words, a variable only exists when it is not equal to nil. Closures and tables make it easy to support some of the key mechanisms required for object-oriented programming, such as data abstraction, virtual functions, inheritance, and overloading.Ĭhat : sendSystemMsg (b, 0 ) -undeclared variable b, no error, but the printed result is nil -Ĭhat : sendSystemMsg (b, 0 ) -declared variable b, the printed result of b is 10 -If you want to delete a global variable, just assign nil as valueĬhat : sendSystemMsg (b, 0 ) -So it's like the variable b has never been used.Language built-in pattern matching Closure The function can also be viewed as a value Support for multi-threading (collaborative processes, not threads supported by the operating system).Automatic memory management Only one generic type of table is provided, which can implement arrays, hash tables, collections and objects.Support procedure-oriented and functional programming).Flexible extension: Lua provides easy to use extension interfaces and mechanisms: these functions are provided by the host language (usually C or C++), and Lua can use them as if they were already built in.File size around 100 kilobytes after compiled, which can be easily embedded in other programs.
