  Integer Bitwise Operation

  Posted by jackyyuk on March 25, 2024 at 7:04 am

  Hello,

  I would like to ask if there is any bitwise operator just like c/c++ in KDB/q+.

  e.g.

  1 | 2 = 3

  1 & 2 = 0

  Thanks,

  Jacky

  Hi @jackyyuk

  At the minute, kdb+/q does not have built-in functions for bitwise and,or,xor operations. However please find below some discussions on this topic and solutions on how to provide bitwise operations.
