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

ParameterTypeDescriptionRequired

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)

Query result:
