public class UltraCalcFunctionIsErr : BuiltInFunctionBase
ISERR(value)
Value is an UltraCalcValue object (perhaps the result of evaluating an UltraCalc expression) thought to be an error value. The ISERR function will return FALSE when value is not an error value, or it is an error but the error value was not applicable.
This is a weaker variation of the more stringent ISERROR function.
