Strongly-typed typo

Sin != Sign

I haven't seen a language yet that imposes (or allows you to impose) a minimal Hamming distance[^] between identifier names. :)

return new Vector3(r * (float)Math.Cos(theta), r * (float)Math.Sign(theta), z);
And I thought I was safe from typos using a strongly-typed language.. :doh: Took me hours to figure this one out.
Shouldn't the compiler be a little more proactively smart enough to throw out a little warning at least w.r.t. context-sensitiveness?

How should he possibly do that? Best solution I can come up with is providing a Math.PolarToCartesian function...

With other tan/cos being used in the same context it can alert if sign is being inadvertently used in lieu of sine?

There is no way it can possibly know beforehand about the existence of a Math class with two methods, Sign and Sine, much less associate Tan and Sine and figure out that the user probably wanted Sine instead of Sign. A source code analysis tool like FxCop could probably do a better job at this.

Cos(x)*Sign(x)is as valid an operation asCos(x)*Sin(x). The latter may be more common overall, but that doesn't mean it has to be for my application. (Besides, I don't believe much in the total greatness of "people who usedMath.Cosalso used the following functions...". Even if it's great for discovering things you might like, you'll have a hard time finding something special.)Agh! Reality! My Archnemesis![^]

As someone who started out coding with 'vi' I find it amusing what people find annoying in modern IDEs. Sad that you wasted so much time, but if you think about everything the IDE was doing to help you ... not a lot to complain about there.

He never said he found the IDE annoying: he was just saying that he mistakenly though that he could avoid typos by using a strongly typed language. Silly man :laugh: Typos are inveitable. Truly so. ;P

nothing to do with IDEs in this one. you could write that code in vi and have the same problem :)
