Operators

 

In Visual Basic, there are four types of operators:

  • Arithmetic Operators

  • Comparison Operators

  • Concatenation Operators

  • Logical Operators

Arithmetic Operators

Operator Description Syntax
^ Operator  Used to raise a number to the power of an  exponent.  result = number ^exponent
* Operator  Used to multiply two numbers.  result = number1 * number2
/ Operator  Used to divide two numbers and return a floating-point result.  result = number1 / number2
\ Operator  Used to divide two numbers and return an integer result.  result = number1 \ number2
Mod Operator  Used to divide two numbers and return only the remainder.  result = number1 Mod number2
+ Operator  Used to sum two numbers.  result = expression1 + expression2
- Operator  Used to find the difference between two numbers or to indicate the negative value of a numeric expression.  result = number1 – number2
 –number

 

 

Comparison Operators

Used to compare expressions.
Syntax:

[result] = [expression1] comparisonoperator [expression2]
[result] = [object1] Is [object2]
[result] = [string] Like [pattern]

Where comparison operators are:

Operator

True if

False if

Null if

< (Less than) expression1 < expression2 expression1 >= expression2 expression1 or expression2 = Null
<= (Less than or equal to) expression1 <= expression2 expression1 > expression2 expression1 or expression2 = Null
> (Greater than) expression1 > expression2 expression1 <= expression2 expression1 or expression2 = Null
>= (Greater than or equal to) expression1 >= expression2 expression1 < expression2 expression1 or expression2 = Null
= (Equal to) expression1 = expression2 expression1 <> expression2 expression1 or expression2 = Null
<> (Not equal to) expression1 <> expression2 expression1 = expression2 expression1 or expression2 = Null
