$and returns the AND operation of two numbers.
Note: The numbers need to be provided in decimal, and are then converted to binary, the AND operation applied, and the answer converted back to decimal.
Synopsis
$and(<N1>,<N2>)
Parameters
- <N1>, <N2> - The numbers, in decimal
Properties
None
Example
//echo -a $and(14,27) ; returns 10 ; 14 is 00001110 when converted to binary ; 27 is 00011011 when converted to binary ; AND 00001010 which is 10 when converted back to decimal
The AND operation returns a 1 when both matching binary bits are 1, otherwise returns 0
//var %n1 14 | var %n2 27 | echo -a $base(%n1,10,2,8) | echo -a $base(%n2,10,2,8) | echo -a $str(-,8) | echo -a $base($and(%n1,%n2),10,2,8)
returns:
00001110 00011011 -------- 00001010
$and returns the answer as a decimal number, so the answer 10 is the decimal representation of binary 1010.
