  • Approximation ≈
  • Double negation ~(~x)
  • Smart match operator in Perl, ~~
  • In PostgreSQL the operator ~~ is equivalent to LIKE
  • In certain programming languages, ~ transforms a value into an integer and takes its complement, and so ~~ (sometimes called 'two tildes' to indicate a form of double negation) is a way to transform a value into an integer.
