Operators Overview
Syntax
^ Not * / \ Mod + - << >> & < <= > >= = <> Is IsNot And AndAlso Or OrElse Xor Eqv Imp
Description
These operators are available for numbers n1 and n2 or strings s1 and s2. If any value in an expression is Null then the expression's value is Null. The order of operator evaluation is controlled by operator precedence.
Parameters
| Operator | Description |
|---|---|
| - n1 | Negate n1. |
| n1 ^ n2 | Raise n1 to the power of n2. |
| n1 * n2 | Multiply n1 by n2. |
| n1 / n2 | Divide n1 by n2. |
| n1 \ n2 | Divide the integer value of n1 by the integer value of n2. |
| n1 Mod n2 | Remainder of the integer value of n1 after dividing by the integer value of n2. |
| n1 + n2 | Add n1 to n2. |
| s1 + s2 | Concatenate s1 with s2. |
| n1 - n2 | Difference of n1 and n2. |
| n1 << n2 | Shift n1 by n2 bits to the left. The number of bits to shift is indicated by the lowest bits of n2: lowest 3 bits when n1 is a SByte/Byte value, lowest 4 bits when n1 is a Integer/UInteger value, lowest 5 bits when n1 is a Long/ULong value, lowest 6 bits when n1 is a Huge_/UHuge_ value. This language element is not VBA compatible. |
| n1 >> n2 | Shift n1 by n2 bits to the right. The number of bits to shift is indicated by the lowest bits of n2: lowest 3 bits when n1 is a SByte/Byte value, lowest 4 bits when n1 is a Integer/UInteger value, lowest 5 bits when n1 is a Long/ULong value, lowest 6 bits when n1 is a Huge_/UHuge_ value. (For signed numbers the sign bit is propagated to the right.) This language element is not VBA compatible. |
| s1 & s2 | Concatenate s1 with s2. |
| n1 < n2 | Return True if n1 is less than n2. |
| n1 <= n2 | Return True if n1 is less than or equal to n2. |
| n1 > n2 | Return True if n1 is greater than n2. |
| n1 >= n2 | Return True if n1 is greater than or equal to n2. |
| n1 = n2 | Return True if n1 is equal to n2. |
| n1 <> n2 | Return True if n1 is not equal to n2. |
| s1 < s2 | Return True if s1 is less than s2. |
| s1 <= s2 | Return True if s1 is less than or equal to s2. |
| s1 > s2 | Return True if s1 is greater than s2. |
| s1 >= s2 | Return True if s1 is greater than or equal to s2. |
| s1 = s2 | Return True if s1 is equal to s2. |
| s1 <> s2 | Return True if s1 is not equal to s2. |
| Not n1 | Bitwise invert the integer value of n1. Only Not True is False. |
| n1 And n2 | Bitwise and the integer value of n1 with the integer value n2. |
| n1 AndAlso n2 | Logical and of n1 with the n2. If n1 is False, n2 is not evaluated. This language element is not VBA compatible and requires the #Language "WWB-COM" setting. |
| n1 Or n2 | Bitwise or the integer value of n1 with the integer value n2. |
| n1 OrElse n2 | Logical or of n1 with the n2. If n1 is True, n2 is not evaluated. This language element is not VBA compatible and requires the #Language "WWB-COM" setting. |
| n1 Xor n2 | Bitwise exclusive-or the integer value of n1 with the integer value n2. |
| n1 Eqv n2 | Bitwise equivalence the integer value of n1 with the integer value n2 (same as Not (n1 Xor n2)). |
| n1 Imp n2 | Bitwise implicate the integer value of n1 with the integer value n2 (same as (Not n1) Or n2). |
