When that is done, the result can be seen in Figure 16 where the Excel intrinsic function can be seen. In this case, a change in the dependent uniform random number argument will fire the Excel inverse function and return an inverse value. Figure Formula String Search Dialog Showing Decoration The mode of random variable operation is important to keep in mind as the results of a simulation can be greatly affected. Formulas Resulting in #DIV/0! There was a widespread problem in Dynamo; it is a division formula involving undefined cells in both the numerator and denominator. If a cell contains the formula =A1/B1 and both cells are blank, the result is #DIV/0! Such a formula may be nonsensical, but it is not an uncommon occurrence when data does not exist for cell A1. Unfortunately, dependences can arise when a collection of items is summed, but really some of the components don’t exist. The vacuous components that, nevertheless, show as #DIV! errors can have unintended and important consequences. A sum is thought to be an error when, in fact, it is not and error. Then, this error condition propagates from the sum (which is unintentionally containing valid and missing components) to other exhibits. In fact, the error condition in the sum is a spurious condition. Arguably, there are times when 0/0 really should not be thought of as division by zero; rather the result should be either NULL or 0. Conditional logic in cells can catch this type of thing, but it is a nuisance to deal with. An example of this phenomenon was the ramifications on the bond summary exhibit.
