binary sequences can represent a wide variety of information, from simple values like numbers and strings to complex data such as images, audio files, and executable code. each bit (0 or 1) in a binary sequence represents either one or zero, which translates into the traditional data types ...
The final value of the decimal number is calculated by adding the individual values from the above table. However, only those values where the bit equals 1 should be added. These values represent the "on" position. The 0s represent the "off" position, so they are not counted in the deci...
hexStr =1x5 string"FF" "10" "C" "400" "89" Thedec2hexanddec2binfunctions also convert arrays of numbers to text representing them as hexadecimal or binary values. However, these functions return character arrays, where each row represents a number from the input numeric array, padded with...

Compares thisSqlBinaryobject to the suppliedSqlBinaryobject and returns an indication of their relative values. Concat(SqlBinary, SqlBinary) Concatenates twoSqlBinarystructures to create a newSqlBinarystructure. Equals(Object) Compares the supplied object parameter to theValueproperty of theSqlBinaryobject...
When enabled, this variable causes the source to write a checksum for each event in the binary log. binlog_checksum supports the values NONE (which disables checksums) and CRC32. The default is CRC32. When binlog_checksum is disabled (value NONE), the server verifies that it is writing onl...
to obtain the variable into which the scanned values should be placed. The type character specifies how the binary data is to be interpreted. Thecounttypically indicates how many items of the specified type are taken from the data. If present, thecountis a non-negative decimal integer or*, ...
