IIF - IIf in Other Programming Languages

IIf in Other Programming Languages

$iif is also present in mIRC script, with similar syntax.

alias testiif { %testiif = 0 echo -a $iif(1,$testiif2,$testiif2) %testiif execution(s) unset %testiif } alias testiif2 { inc %testiif | return testing $!iif: }

calling /testiif will print out "testing $iif: 1 execution(s). mIRC's $iif acts more like C's ?: than IIf in VB since it won't pre-evaluate both.

IIF is a function in dBase and xBase. (1992 and before.)

iif is also a compiler magic function of Oxygene. It is not a real function and is at compile time unrolled to conditional statements.

var someString := iif(someInt > 35, 'Large', 'Small');

In this example a new strong type string named "someString" is created (using Type inference) and the iif function will fill it depending on the outcome of the boolean expression.

New 2012 year's release of SQL Server also includes implementation of IIF function:

DECLARE @a INT = 45; DECLARE @b INT = 40; SELECT IIF ( @a > @b, 'TRUE', 'FALSE' ) AS RESULT;

IIF in C:

printf("number %d is%s even", num, num % 2 ? " not" : "");
