#BASIC SYMBOL FOR DOES NOT EQUAL CODE#
If your code uses any of these operators on such a class or structure, be sure you understand the redefined behavior. The following example shows a typical binary sort order.Ī, >=, =, ) can be overloaded, which means that a class or structure can redefine their behavior when an operand has the type of that class or structure. The sort order is determined by the code page. Option Compare Binary bases string comparisons on a sort order derived from the internal binary representations of the characters. When you compare strings, the string expressions are evaluated based on their alphabetical sort order, which depends on the Option Compare setting.

#BASIC SYMBOL FOR DOES NOT EQUAL MOD#
This could lead to unexpected results from certain operations, such as value comparison and the Mod Operator. When you work with floating-point numbers, keep in mind that they do not always have a precise representation in memory. It is safer to test whether the absolute value of the difference between the two numbers is less than a small acceptable tolerance. For this reason, you should take care when using equality ( =) to compare two floating-point variables. Such fractional value loss may cause two values to compare as equal when they are not. For Decimal expressions, any fractional value less than 1E-28 might be lost. Similarly, when you compare an expression of type Decimal to an expression of type Single or Double, the Decimal expression is converted to Single or Double. This behavior is opposite to the behavior found in Visual Basic 6. When you compare an expression of type Single to one of type Double, the Single expression is converted to Double. The Is operator, the IsNot operator, and the Like operator have specific comparison functionalities that differ from the operators in the preceding table. The = Operator is also used as an assignment operator. The following table contains a list of the relational comparison operators and the conditions that determine whether result is True or False. Any String expression or range of characters. A Boolean value representing the result of the comparison. Syntax result = expression1 comparisonoperator expression2 The relational comparison operators are discussed in detail on this page. Is, IsNot, and Like are discussed in detail on separate Help pages. These operators compare two expressions to determine whether or not they are equal, and if not, how they differ. The following are the comparison operators defined in Visual Basic.
