* Operator (Visual Basic)
Multiplies two numbers.
Syntax
number1 * number2
Parts
Term | Definition |
---|---|
number1 |
Required. Any numeric expression. |
number2 |
Required. Any numeric expression. |
Result
The result is the product of number1
and number2
.
Supported Types
All numeric types, including the unsigned and floating-point types and Decimal
.
Remarks
The data type of the result depends on the types of the operands. The following table shows how the data type of the result is determined.
Operand data types | Result data type |
---|---|
Both expressions are integral data types (SByte, Byte, Short, UShort, Integer, UInteger, Long, ULong) | A numeric data type appropriate for the data types of number1 and number2 . See the "Integer Arithmetic" tables in Data Types of Operator Results. |
Both expressions are Decimal | Decimal |
Both expressions are Single | Single |
Either expression is a floating-point data type (Single or Double) but not both Single (note Decimal is not a floating-point data type) |
Double |
If an expression evaluates to Nothing, it is treated as zero.
Overloading
The *
operator 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. If your code uses this operator on such a class or structure, be sure you understand its redefined behavior. For more information, see Operator Procedures.
Example
This example uses the *
operator to multiply two numbers. The result is the product of the two operands.
Dim testValue As Double
testValue = 2 * 2
' The preceding statement sets testValue to 4.
testValue = 459.35 * 334.9
' The preceding statement sets testValue to 153836.315.
