Division Operator (/)
Description Divides two numbers and returns a floating-point result
Usage result = number1 / number2
Arguments result
Any numeric variable.
number1
Any valid numeric expression.
number2
Any valid numeric expression.
Return A floating point number.
Remarks If one or both expressions are Null expressions, result is Null. Any expression that is Empty is
treated as 0.
See also Multiplication Operator(*), Integer Division Operator(\)
Example: Dim a, b
a = 3
b = A / 2 ‘ The result b is equal to 1.5
Eqv Operator (Eqv)
Description Performs a logical equivalence on two expressions, checking if both expressions evaluate to the
same value
Usage result = expression1 Eqv expression2
Arguments result
Any numeric variable.
expression1
Any expression, must evaluate to True, False, or Null
expression2
Any expression, must evaluate to True, False, or Null
Return Returns True is both expressions evaluate to the same value (True or False)
Remarks If either expression is Null, result is also Null. When neither expression is Null, result is
determined according to the following table:
If expression1 is And expression2 is Then result is
True True True
True False False
False True False
False False True
The Eqv operator performs a bitwise comparison of identically positioned bits in two numeric
expressions and sets the corresponding bit in result according to the following table:
If bit in expression1 is And bit in expression2 is Then result is
0 0 1
0 1 0
1 0 0
1 1 1
Example: Dim cond1, cond2, cond3
cond1 = False
cond2 = False
cond3 = cond1 Eqv cond2 ‘ cond3 is set to True
Example a = 5 ‘ Bitwise 5= 0000 0000 0000 0101
b = 4 ‘ Bitwise 4 = 0000 0000 0000 0100
MyResult = a Eqv b ‘ Result = -2 = 1111 1111 1111 1110
