Evaluate

Unit:SDL_math2
Class:TMathExpression
Declaration:function Evaluate: Variant;

The method Evaluate interprets the expression specified by the property Expression and calculates the result of it. If the function parser encounters a variable name, it triggers an OnVarRequest event asking for the corresponding value.

The actual type of the result depends on the type of variables and the operators applied to them.
