Manual

Applies a user defined formula to the inputs and outputs the value on the Out port. The formula syntax follows the mu parser format as specifed here: http://muparser.beltoforion.de/ with a few additional functions such as the Modulus function mod(a, b) and the addition of vector component access in the Vector Formula module.

Skins

Medium

4 inputs, medium-sized formula textfield. Can be resized.

Small

2 inputs, slightly smaller formula textfield. Can be resized.

Formula language

Currently a list of the available commands is available here: http://beltoforion.de/article.php?a=muparser&hl=en&p=features&da=1.

For ease of use it is replicated here, however, as always you are reeferred to the original source.
