Bitwise functions
Bitwise operations performing on long expressions.
bitwiseAnd
Calculates the bitwise and between two long expressions.
Syntax
bitwiseAnd(long expression, long expression)
Parameters
| Parameter | Type | Description | Required |
|---|---|---|---|
firstExpression | long | The first long expression for the binary operation. | required |
secondExpression | long | The second long expression for the binary operation. | required |
Returns
The data type of the returned value is long.
Examples
Example 1

bitwiseShiftLeft
Shifts the long expressions by the number of given bits to the left.
Syntax
bitwiseShiftLeft(long expression, long expression)
Parameters
| Parameter | Type | Description | Required |
|---|---|---|---|
expression | long | The long expression that will be bitwise shifted to the left. | required |
numberOfBits | long | The number of bits by which the expression will be shifted left. | required |
Returns
The data type of the returned value is long.
Examples
Example 1
data record(a = 0, bits = 1),record(a = 1, bits = 1),record(a = 1, bits = 2),record(a = 9223372036854775807, bits = 1),record(a = -9223372036854775808, bits = 1)| fieldsAdd bitwiseShiftLeft(a, bits)

bitwiseShiftRight
Shifts the long expression by number of given bits to the right. It has an optional parameter ignoreSign, that defines, if the sign bit should be ignored. If the parameter is false, it can be compared to >> in Java, otherwise to >>>.
Syntax
bitwiseShiftRight(long expression, long expression, ignoreSign: boolean)
Parameters
| Parameter | Type | Description | Required |
|---|---|---|---|
expression | long | The long expression that will be bitwise shifted right. | required |
numberOfBits | long | The number of bits by which the expression will be shifted right. | required |
ignoreSign | boolean expression | The boolean expression that indicates if the sign bit should be ignored (treated like any bit) while shifting, If false, the sign bit is preserved and just the other bits are shifted. | optional |
Returns
The data type of the returned value is long.
Examples
Example 1
data record(a = 0, bits = 1),record(a = 1, bits = 1),record(a = 1, bits = 2),record(a = 9223372036854775807, bits = 1),record(a = -9223372036854775808, bits = 1),record(a = -1, bits = 2)| fieldsAdd bitwiseShiftRight(a, bits, ignoreSign: false),bitwiseShiftRight(a, bits, ignoreSign: true)
