Operator Or= (Inclusive Disjunction And Assign)
Performs a bitwise-or (inclusive disjunction) and assigns the result to a variable
lhs Or= rhs
lhs
This operator performs a bitwise-or and assigns the result to a variable (for conversion of a boolean to an integer, false or true boolean value becomes 0 or -1 integer value). It is functionally equivalent to:
Or= compares each bit of its operands, lhs and rhs, and if either bits are 1, then the corresponding bit in the first operand, lhs, is set to 1, otherwise it is set to 0.
This operator can be overloaded for user-defined types.
Syntax
Usage
lhs Or= rhs
Parameters
lhs
The variable to assign to.
T1Any numeric or boolean type.
rhsThe value to perform a bitwise-or (inclusive disjunction) with lhs.
T2Any numeric or boolean type.
Description
This operator performs a bitwise-or and assigns the result to a variable (for conversion of a boolean to an integer, false or true boolean value becomes 0 or -1 integer value). It is functionally equivalent to:
lhs = lhs Or rhs
Or= compares each bit of its operands, lhs and rhs, and if either bits are 1, then the corresponding bit in the first operand, lhs, is set to 1, otherwise it is set to 0.
This operator can be overloaded for user-defined types.
Example
Dim As UByte a = &b00110011
Dim As UByte b = &b01010101
a Or= b
'' Result a = &b01110111
Print Bin(a)
Dim As UByte b = &b01010101
a Or= b
'' Result a = &b01110111
Print Bin(a)
Dialect Differences
- In the -lang qb dialect, this operator cannot be overloaded.
Differences from QB
- New to FreeBASIC
