## Effect

Performs a bitwise EQV-operation (logical equivalence) between two expressions.

The bit is set if both bits are equal. For each bit, the results are:

0 EQV 0 = 1

0 EQV 1 = 0

1 EQV 0 = 0

1 EQV 1 = 1

## Syntax

<Value> EQV <Value>

## Parameter

**<Value>** is a value between -32768 and 32767. It can also be a numeric variable or an mathematical expression.

Notes:

- If you use binary expressions, it is best to put the first expression in parenthesis to avoid the bug in interpreter that causes a syntax error. This problem does not happen with decimal, hexadecimal or octal expressions.

- When the expression is performed in a condition (IF...THEN...ELSE or IF...GOTO...ELSE), if the result of the whole expression is zero the value is taken as false, otherwise it's taken as true.

## Examples

PRINT 15 EQV 11

-5

Binary explanation:

0000000000001111 0000000000001011 EQV ---------------- 1111111111111011

-5 is actually the number 65531

PRINT 5 EQV 13

-9

Binary explanation:

0000000000000101 0000000000001101 EQV ---------------- 1111111111110111

-9 is actually the number 65527

PRINT &B00001111 EQV &B11110001

Syntax error

PRINT (&B00001111) EQV &B11110001

-255

-255 is actually the number 65281
