Result type: INTEGER or BIGINT Syntax: BIN_AND (number [, number ...]) Important Internal functions If the external function BIN_AND is declared in your database, it will override the internal function. To make the internal function available, DROP or ALTER the external function (UDF). Available in: DSQL, PSQL Added in: 2.1 BIN_OR() Description: Returns the result of the bitwise OR operation on the argument(s). Result type: INTEGER or BIGINT Syntax: BIN_OR (number [, number ...]) Important If the external function BIN_OR is declared in your database, it will override the internal function. To make the internal function available, DROP or ALTER the external function (UDF). Available in: DSQL, PSQL Added in: 2.1 BIN_SHL() Description: Returns the first argument bitwise left-shifted by the second argument, i.e. a
Added in: 2.1 Internal functions Description: Returns the first argument bitwise right-shifted by the second argument, i.e. a >> b or a/2^b. Result type: BIGINT Syntax: BIN_SHR (number, shift) • The operation performed is an arithmetic right shift (SAR), meaning that the sign of the first operand is always preserved. Available in: DSQL, PSQL Added in: 2.1 BIN_XOR() Description: Returns the result of the bitwise XOR operation on the argument(s). Result type: INTEGER or BIGINT Syntax: BIN_XOR (number [, number ...]) Important If the external function BIN_XOR is declared in your database, it will override the internal function. To make the internal function available, DROP or ALTER the external function (UDF). Available in: DSQL, PSQL Added in: 2.0 Changed in: 2.1 BIT_LENGTH() Description: Gives the length in bits of the input string. For multi-byte character sets, this may be less than the number of characters times 8 times the “formal” number of bytes per character as found in RDB $CHARACTER_SETS. Note With arguments of type CHAR, this function takes the entire formal string length (e.g. the declared length of a field or variable) into account. If you want to obtain the “logical” bit length, not counting the trailing spaces, right-TRIM the argument before passing it to BIT_LENGTH. 128
