### Operator EQV (Equivalence)

Returns the bitwise-and (equivalence) of two numeric values

**Syntax:**

**Usage:**

`
`

*result*=

*lhs*

**Eqv**

*rhs*

**Parameters:**

*lhs*
The left-hand side expression.

*T1*
Any numeric or boolean type.

*rhs*
The right-hand side expression.

*T2*
Any numeric or boolean type.

*Ret*
A numeric or boolean type (varies with

`and`*T1*`).`*T2***Return Value:**

Returns the bitwise-equivalence of the two operands.

**Description:**

This operator returns the bitwise-equivalence of its operands, a logical operation that results in a value with bits set depending on the bits of the operands (for conversion of a boolean to an integer, false or true boolean value becomes 0 or -1 integer value).

The truth table below demonstrates all combinations of a boolean-equivalence operation:

No short-circuiting is performed - both expressions are always evaluated.

The return type depends on the types of values passed.

This operator can be overloaded for user-defined types.

The truth table below demonstrates all combinations of a boolean-equivalence operation:

Lhs Bit | Rhs Bit | Result |

0 | 0 | 1 |

1 | 0 | 0 |

0 | 1 | 0 |

1 | 1 | 1 |

No short-circuiting is performed - both expressions are always evaluated.

The return type depends on the types of values passed.

`Byte`,`Ubyte`and floating-point type values are first converted to`Integer`. If the left and right-hand side types differ only in signedness, then the return type is the same as the left-hand side type (`), otherwise, the larger of the two types is returned. Only if the left and right-hand side types are both`*T1*`Boolean`, the return type is also`Boolean`.This operator can be overloaded for user-defined types.

**Examples:**

Dim As UByte a = &b00110011

Dim As UByte b = &b01010101, c

c = a Eqv b '' c = &b10011001

Dim As UByte b = &b01010101, c

c = a Eqv b '' c = &b10011001

**Dialect Differences:**

- In the
*-lang qb*dialect, this operator cannot be overloaded.

**Differences from QB:**

- None
