Sometimes in the numeric formatted cells, as a result of various calculations, it is possible to have returned as a result the Anaplan special numbers: Infinity, -Infinity, or NaN (Not a Number).
If the numeric line item with this issue is also an input for other formulas, the final result could be altered. To solve this issue a solution is to convert these Anaplan special numbers in zero values.
Convert Infinity and -Infinity:
First thing is to have calculated the "Infinity" value in a system module without any lists.
This can be achieved in different ways by applying one of the formulas in a numeric formatted line-item: DIVIDE(1,0) or VALUE("Infinity").
Then it can be applied, in sequence, to the following Anaplan functions:
Convert numeric line-item in positive number (function: ABS).
Compare the result in Step 1 if it is NOT equal with the Infinity value calculated in the system module
If TRUE then consider the numeric value, ELSE consider 0
Example: IF ABS(Value num) <> 'SY00 Params'.'Val. Infinity' THEN Value num ELSE 0
Note: ABS function is useful to solve in one comparison both Infinity (positive) and -Infinity (negative)
Convert NaN: Apply in sequence the following Anaplan functions/statements:
Convert numeric line-item in positive number (function: ABS)
Compare result Step 1 if it is greater or equal with zero. NaN value will return false.
Consider the initial value of the line-item if Step 1 is greater or equal with zero else consider zero (on ELSE the NaN will be converted to zero).
Example: IF ABS(Value num) >= 0 THEN Value num ELSE 0
Notes:
- ABS function is useful to solve in one comparison both positive and negative numbers
- NaN=NaN, NaN>=0, NaN<=0 comparisons will always return FALSE. This is why it is needed to check with zero the numeric values.
