Operator OR= (Inclusive Disjunction and Assign)
- Source: https://www.freebasic.net/wiki/wikka.php?wakka=KeyPgOpCombineOr
- Last revised: 2019-09-27
Performs a bitwise-or (inclusive disjunction) and assigns the result to a variable
Syntax
` declare operator Or= ( byref lhs as T1, byref rhs as T2 )
`
Usage
` lhs Or= rhs
`
Parameters
lhs
The variable to assign to.
T1
Any numeric or boolean type.
rhs
The value to perform a bitwise-or (inclusive disjunction) with lhs.
T2
Any 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 as a member Operator using the appropriate syntax.
Note: Similarly to the operator '=[>]' (assign), the alternative symbol 'Or=>' can be also used.
Examples
start GeSHi
Dim As UByte a = &b00110011
Dim As UByte b = &b01010101
a Or= b
'' Result a = &b01110111
Print Bin(a)end GeSHi
Dialect Differences
- In the -lang qb dialect, this operator cannot be overloaded.
