An example of a simple expression is : LN(X)+SIN(10/2-5)

When parsed, this expression will be represented as: since the SIN(10/2-5) is in fact SIN(0) which is a constant and is 0.

Thus, in a loop, if you change the value of X and ask for the value of the expression, it will be evaluated quite fast since SIN(10/2-5) is not dependent on X.

X and Y are predefined variables. You can create your own variables as needed.

There are many predefined mathematical functions. They are listed in documentation. You can create your functions that take one or two parameters as needed.
