is there an if statement in pd?

eg

if (value < 0) do something

[sfruit/if < 0]

...
|
| [!= 0]
| |
[spigot]
|
...

check out standard operators like [==], [>], [<], as usual right click to learn more and see what else is available. also give a look at [expr] for more complex statements (full syntax available here).

thanks guys very usefull.
is there anywhere i can see a list of all the syntax available in pd?
