Evaluate Method (UltraCalcFunctionValue)

Evaluates the function against the argument on the number stack.

Syntax

Visual Basic

'Declaration
 
Protected Overrides Function Evaluate( _
   ByVal numberStack As UltraCalcNumberStack, _
   ByVal argumentCount As Integer _
) As UltraCalcValue

C#

protected override UltraCalcValue Evaluate( 
   UltraCalcNumberStack numberStack,
   int argumentCount
)

Parameters

numberStack

Formula number stack containing function arguments.

argumentCount

Denotes the number of function arguments pushed onto the number stack.

Return Value

An UltraCalcValue that represents the result of the function evaluation.

Remarks

Returns an error if the UltraCalcValue argument at the top of the number stack was an error.

Returns a value conversion into a double-precision numeric type if the incoming text can be interpreted as a numeric value (possibly after filtering off thousands separators, decimal separators, currency symbols, exponents and signs.)

Returns a numeric conversion from another numeric type if the incoming argument was not text (sometimes when the result of such a conversion is poorly defined this may defy an application's expectations, for example, a DATEVALUE may convert into a numeric value of ticks.)
