Operator Imp= (Implication And Assign)
Performs a bitwise-imp (implication) and assigns the result to a variable
lhs Imp= rhs
lhs
This operator performs a bitwise-imp 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:
Imp is a bitwise operator which is the same as (Not lhs) Or rhs. Imp= compares each bit of its operands, lhs and rhs, and if the bit in lhs is 0 or the bit in rhs is 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 Imp= rhs
Parameters
lhs
The variable to assign to.
T1Any numeric or boolean type.
rhsThe value to perform a bitwise-imp (implication) with lhs.
T2Any numeric or boolean type.
Description
This operator performs a bitwise-imp 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 Imp rhs
Imp is a bitwise operator which is the same as (Not lhs) Or rhs. Imp= compares each bit of its operands, lhs and rhs, and if the bit in lhs is 0 or the bit in rhs is 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 Imp= b
'' Result a = &b11011101
Print Bin(a)
Dim As UByte b = &b01010101
a Imp= b
'' Result a = &b11011101
Print Bin(a)
Dialect Differences
- In the -lang qb dialect, this operator cannot be overloaded.
Differences from QB
- New to FreeBASIC
