/= Operator (Visual Basic)

  • Article

Divides the value of a variable or property by the value of an expression and assigns the floating-point result to the variable or property.

Syntax

VB 
variableorproperty /= expression

Parts

variableorproperty
Required. Any numeric variable or property.

expression
Required. Any numeric expression.

Remarks

The element on the left side of the /= operator can be a simple scalar variable, a property, or an element of an array. The variable or property cannot be ReadOnly.

The /= operator first divides the value of the variable or property (on the left-hand side of the operator) by the value of the expression (on the right-hand side of the operator). The operator then assigns the floating-point result of that operation to the variable or property.

This statement assigns a Double value to the variable or property on the left. If Option Strict is On, variableorproperty must be a Double. If Option Strict is Off, Visual Basic performs an implicit conversion and assigns the resulting value to variableorproperty, with a possible error at run time. For more information, see Widening and Narrowing Conversions and Option Strict Statement.

Overloading

The / Operator (Visual Basic) can be overloaded, which means that a class or structure can redefine its behavior when an operand has the type of that class or structure. Overloading the / operator affects the behavior of the /= operator. If your code uses /= on a class or structure that overloads /, be sure you understand its redefined behavior. For more information, see Operator Procedures.

Example

The following example uses the /= operator to divide one Integer variable by a second and assign the quotient to the first variable.

VB 
Dim var1 As Integer = 12
Dim var2 As Integer = 3
var1 /= var2
' The value of var1 is now 4.
