Using >= in formulas

Parameter less than equals

When creating a Family and using formulas, have you ever encountered a situation like this;

A = 100
B = 200

Is A >= B?
i.e. Is ‘A’ greater than, or equal to ‘B’?

You’ll notice in the Revit Help that the syntax >= is not valid in formulas. So how do you get around such a simple problem?
The answer is to negate a formula which does use a valid syntax.

Instead try:
not ( A < B )
