*"One Thousand Five Hundred" =~ "(T[Expressions Examples^ ])"
returns: Thousand

  • "One Thousand Five Hundred" =~ "T[Expressions Examples^ ]"
    returns: 8
  • "One Thousand Five Hundred" : "T[Expressions Examples^ ]"
    returns: 0
  • "8015551212" : "(...)"
    returns: 801
  • "3075551212":"...(...)"
    returns: 555
  • ! "One Thousand Five Hundred" =~ "T[Expressions Examples^ ]"
    returns: 0
    (because it applies to the string, which is non-null, which it turns to "0", and then looks for the pattern in the "0", and doesn't find it)
  • !( "One Thousand Five Hundred" : "T[Expressions Examples^ ]+" )
    returns: 1
    (because the string doesn't start with a word starting with T, so the match evals to 0, and the ! operator inverts it to 1 )
  • 2 + 8 / 2
    returns: 6
    (because of operator precedence; the division is done first, then the addition)
  • 2+8/2
    returns: 6
    Spaces aren't necessary
  • (2+8)/2
    returns: 5
    of course
  • (3+8)/2
    returns: 5.5
  • TRUNC((3+8)/2)
    returns: 5
  • FLOOR(2.5)
    returns: 2
  • FLOOR(-2.5)
    returns: -3
  • CEIL(2.5)
    returns: 3
  • CEIL(-2.5)
    returns: -2
  • ROUND(2.5)
    returns: 3
  • ROUND(3.5)
    returns: 4
  • ROUND(-2.5)
    returns: -3
  • RINT(2.5)
    returns: 2
  • RINT(3.5)
    returns: 4
  • RINT(-2.5)
    returns: -2
  • RINT(-3.5)
    returns: -4
  • TRUNC(2.5)
    returns: 2
  • TRUNC(3.5)
    returns: 3
  • TRUNC(-3.5)
    returns: -3

Of course, all of the above examples use constants, but would work the same if any of the numeric or string constants were replaced with a variable reference ${CALLERID(num)}, for instance.
