Test if a number value is NAN (not a number) or ND (not defined)
Member of Floating Point Intrinsic Functions (PRIM_LIBI.IFloatingPointIntrinsics)
|Result||*Result (Optional)||Boolean||True if the variable is NAN or ND|
Certain floating point calculations may return values that are not recognised numbers. The value returned may be either an NAN (not a number) or an ND (non-determinate). IsNANorNd can be used after the calculation and will return True if the variable is not a number.
In the In this example, if #String contained ?ABC?, the result would be 3
#Result := #Float.ArcCosine If (#Result.IsNANorND) * Error handling
