[texhax] Text in Math Mode

[Robin Fairbairns]

>     I wrote the following line in LaTeX:
>         $$a = b~iff~a \geq b~and a \leq b$$
> I would like LaTex to generate something like:
>         a = b iff a >= b and a <= b
> The problem is, LaTeX is adding a small amount of white space in the word
> iff. What can I do to turn this off? I tried putting curly braces around iff
> but that does not seem to help.
