[Qgis-user] If/Else with raster calculator

Hi List,
How do I do a If/Else with the raster calculator *and* have the ability to
set arbitrary values for both conditions.

For example, similar to the below psuedocode:

If(condition):
>   Cell = 9
> else:
>   Cell = 68


This seems like it'd be a core part of a raster calculator but all I can
find is the ability to get True/False and then cludge around that, i.e.
with:

> (condition) * 9


What am I missing? Good tutorials welcome (the ones I've found don't show
anything beyond true/false).
Thanks,
Jonathan
