CampaignCriterion.bidModifier returned with many decimal places normal?

[JC Lee]

Hi,

I am doing a CampaignCriterionService->mutate() operation with a bidModifier value of 1.05. The return value I get back is 1.0499999523163. Is this normal?

Shouldn't the API round it up to 2 decimal places before sending it back?

Hi,

Because there are only a finite number of double-precision numbers, you cannot represent all numbers in double-precision storage. On any system, there is a small gap between each double-precision number and the next larger double-precision number. Because of this, many numbers will have small changes to allow them to be stored. I suggest that you round up the value returned in the response to two decimal digits as shown in the SetBidModifier.php example.
