EQV                                                                         Operator

result = x EQV y

Description

EQV returns the logical equivalence of two expressions. result is TRUE, if both expressions x and y evaluate to TRUE or both expressions x and y evaluate to FALSE, otherwise, result is FALSE.

EQV also does a bitwise comparison of two numeric expressions. Each bit in result is set to 1 if both corresponding bits in x and y are 1 or both corresponding bits in x and y are 0, otherwise it is set to 0.

Example

REM EQV Example

'EQV performs logical and bitwiseequivalence

DIM Test1, Test2, Test3, x, y

x = 4

y = 9

Test1 = x < 0 EQV y < 10

Test2 = x > 0 EQV y > 10

Test3 = x < 0 EQV y > 10

PRINT "Logical:"

PRINT "  x < 0 EQV y < 10 = " & Test1

PRINT "  x > 0 EQV y > 10 = " & Test2

PRINT "  x < 0 EQV y > 10 = " & Test3

PRINT "Bitwise:"

PRINT "  x EQV y = " & (x EQV y)

Output

Logical:

  x < 0 EQV y < 10 = False

  x > 0 EQV y > 10 = False

  x < 0 EQV y > 10 = True

Bitwise:

  x EQV y = -14
