Operator Imp (Implication)
Returns the bitwise-and (implication) of two numeric values
Syntax
`
Declare Operator Imp ( ByRef lhs As T1, ByRef rhs As T2 ) As Ret
`
Usage
`
result = lhs Imp 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 `T1` and `T2`).
Return Value
Returns the bitwise-implication of the two operands.
Description
This operator returns the bitwise-implication 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-implication operation:

Lhs Bit | Rhs Bit | Result
0 | 0 | 1
1 | 0 | 0
0 | 1 | 1
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 (`T1`), otherwise, the larger of the two types is returned. Only if the left and right-hand side types are both `Boolean`, the return type is also `Boolean`.
This operator can be overloaded for user-defined types.
Example
`
Dim As UByte a, b, c
a = &b00001111
b = &b01010101
c = a Imp b '' c = &b11110101
`
