Latex Equation Help: Aligning "f(x)" & "0

[DrCrab]

Just a quick latex question, does anyone know the command for equations like:

f(x) = x if x < 1
0 if x >= 1

where the x and the 0 line up, and you'd have a large { spread over the options?

Thanks for your help.

\begin{cases} is a good start. Found it on this page: http://meta.wikimedia.org/wiki/Help:Displaying_a_formula

That's exactly what I was looking for.

Thanks a lot for your help :)
