Mathematical Expressions in Numerical Inputs

In any VRED function that allows numerical input, you can use a mathematical expression in addition to numeric values.

• Valid operators are: +, -, *, /, and ( ).
• Relative operators, that change the current value, are: +=, -=, *=, and /=.

Here is an example of using valid and relative operators: To divide a current value of 10 by 2, enter as 10/2 or /=2. The equal sign represents the current value.

If the expression is not valid, the input field has a yellow border. Once a valid expression is entered, the input field has the normal orange border when the mouse is hovered over it.
