I voted for '!=', but I also know of '<>' and '-ne'. |

!= because the exclamation point is widely used in programing to mean "does/is not". |

The last two are an attempt to replicate the standard handwritten symbol, which does exist in LaTeX as a single symbol: Attachment: not equal.png [ 220 Bytes | Viewed 1919 times ] Lacking such a symbol, the proper formal way to express the relationship is to use the logical NOT operator before the equal sign. != |

Fortunately it exists in unicode, so if you wanna use it, here you go: ≠ http://www.fileformat.info/info/unicode ... /index.htm |

Now we need a unicode for "Does not want!"

!= I've seen <> and it always confuses me for a second. |

I've used != and <> I believe I picked up the use of <> from BASIC. |

BASIC is the only language I'm aware of that uses "<>". Trivia: in Intel-style x86 and x64 assembly, you do (in)equality testing with a combination of the cmp or sub instruction followed by jz/je or jnz/jne. Code: cmp eax, 7h
jne <wherever> |

Non of the above. I typically use |= when typing. Tho /= is a close runner up. |

I want to say that Pascal uses (or used to use) <> for an inequality operator. |

In my old FORTRAN days it was .ne. but now it's != |

I voted for !=, but my job has me using <> an awful lot. Oh, also ... NEQ. |

gah... i was just trying to be funny.. (poorly apparently) My bubbles all burst a long long time ago... |

Sorry bout that. It's totally funny, now that I know it's not a deeply-held personal belief. |

Definitely !-, followed by <>. I originally learned to program in BASIC which uses <>, but many years of programming in C, then C++, then Java, have ingrained !=. |

!= clearly means you are excited that it is equal. My programming days are long behind me. I use /= |

!= and I think as above both Pascal and Basic use <> but I haven't used that in a longgggggg time. |
