How to use Param-O Conditional Math Nodes

[4hotshoes]

In Param-o, there are "equal", "not equal", "Lesser", "Greater" and orther Math Nodes that evaluate two values and return a true of false. What can I do with these? They seem to almost look like "if, than" conditional statements. Can I use one of the values being compared? This is not clear in the manual. Are there better explanations with examples?

I think they are for simple binary (on/off) control. For example you could do a comparison to show or hide node output, although there are probably work arounds for other options.

I found a way around the problem. If the conditions of comparison ≠ zero, then one shape will remain visible, while the other shape is invisible, However, if the conditions of comparison = 0, then the other shape shows while the first becomes invisible.
