*"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.
