The =, <> ,<, <=, >, >= functions are equivalent to compareEQ, compareNE, compareGT, compareGE, compareLT, and compareLE comparison functions. The resulting value is a Boolean value of true if the relational operator results in a true comparison otherwise the resulting value is false.


Use the comparison functions when you wish to compare two Vectors and determine if they are equal, not equal, less than, less than or equal to, greater than, greater than or equal to and you wish the result to be expressed as a Boolean value (true or false). For two Vectors to compare equal, all values have to be equal. The less-than < condition is satisfied only if the first Vector is less than the second Vector. The greater-than > condition is satisfied only if the first Vector is greater-than the second Vector.



Expression: (= obj1 obj2)

Arguments Name Type Description
Argument:obj1Void Character Date Complex First object to be compared. Must be a native data type.
Argument:obj2Void Character Date Complex Second object to be compared. Must be a native data type.


Returns true if the comparison is true, false if the comparison is false.
