System Variables

Before evaluation, the following variables are automatically set.

Variable Name	Value
`Pi`	Mathematical constant pi = circumference/diameter.
`E`	Mathematical constant e = `lim_h->0(1+h)^1/h`.
`uSteps` `vSteps` `tSteps`	Returns the steps as set in the scene editor dialog.

Note: The variable names (as anything else) are case sensetive.

Operators

Priority Level	Operator
Level 0	`==`, `!=` `<`, `>` `<=`, `>=`
Level 1	`+`, `-`
Level 2	`*`, `/`, `%` (modulo)
Level 3	`^` (power)

Functions

Others	abs, floor/box, ceil, sign, frac

Note: Unlike Arnab's Graph Explorer (see http://geocities.com/hirak_99/goodies/graph.html), 3D Graph Explorer distinguishes between cases, so z=Sin(x) does not work, but z=sin(x) works.
