Game Maker Programming/Expressions

Expressions are comparisons of two things. An example of an expression would be (8 > 6) Types of Expressions Expressions can be real number like 6 or 7, 'hexadecimal numbers', strings or more complicated expressions. By default all text is considered a Variables though if the text was in single or double quotes it would be a string. Any number in an expression is considered a real number unless it has a $ sign in front of it. If it had a $ in front of it then it is a 'hexadecimal number' Operators An operator is a symbol used for the comparison of two things in an expression. In (8 > 6) the > sign is the operator. There are many different types of operators. For expressions, the following binary operators exist: && means "and". For example "if(pi=3.14 && 3+4=7)" || means "or". For example "if(x=0 || y=0)" ^^ means "xor". example "if(x=32 ^^ y=27)" < means "less than". > means "greater than". <= means "less than or equal to". >= means "greater than or equal to". ! means "Not". For example "if !(Variable=5)"
