It's most commonly used in assignment operations, although it has other uses as well. The ternary operator ? is a way of shortening an if-else clause, and is also called an immediate-if statement in other languages (IIf(condition,true-clause,false-clause) in VB, for example). For example: bool Three = SOME_VALUE; int x = Three ? 3 : 0; is the ...

2011年6月7日 · Actually ternary is the type of operator (i.e. it has 3 parts). The name of that specific ternary operator is the conditional operator. There just happens to only be one ternary operator in JS so the terms get misused. –

2010年11月23日 · I've read comments saying not to use the ternary operator because it's confusing, but that is a bad reason to not use something. By the same logic we shouldn't use regular expressions, range operators (' .. ' and the seemingly unknown "flip-flop" variation).

For those of you who use ASP.net with VB razor the ternary operator is also possible. It must be, as well, inside a razor expression: @(Razor_Expression) and the ternary operator works as follows: If(BooleanTestExpression, "TruePart", "FalsePart") The same code example shown here with VB razor looks like this:

2015年7月10日 · @Damien_The_Unbeliever That's technically true, but it's often called ternary operator. "Since this operator is often the only existing ternary operator in the language, it is sometimes simply referred to as "the ternary operator". In some languages, this operator is referred to as "the conditional operator." Ternary operation –

2011年4月8日 · If anyone is looking for a vectorized ternary (operating on logical arrays and number arrays), here's a really simple one (it is not short-circuiting): vectorizedTernary = @(cond, resTrue, resFalse) cond.*resTrue + (1-cond).*resFalse

2012年1月20日 · The conditional (ternary) operator is useful when you want to use the result. If the result is going to be discarded, as it is here, it's clearer (and, as you've seen, less error-prone) to use an if/else statement:

2024年11月14日 · @laughedelic, yeah I put this up before the OP had a compilable example. I assumed that the title was correct and a ternary operator was the goal. I see now that the example code is more complicated, and yet my answer was accepted. Go figure. I think the OP is confused on a number of fronts. I still don't know what "1.5" is supposed to be. –

2018年3月28日 · A ternary operator is any operator that takes three operands, much like a binary operator takes two and a unary operator takes one. The ?: operator is a specific example of a ternay operator, not the definition. –

2017年1月26日 · For Cg the situation is similar, also here the ternary conditional operator is a vector operator. (documentation): Unlike C, side effects in the expressions in the second and third operands are always executed, regardless of the condition. In ESSL and GLSL the ternary operator will always lead to branching.
