Unlike built-in floating-point numbers, the decimal module provides a way to adjust the precision to use in a given calculation that involves Decimal numbers. The precision defaults to 28 places, but you can change it to meet your problem requirements. A quick way to perform calculations with...

Now lets say that we actually need to process 2 more field calculations to complete the update of this feature class. One calculation needs to add two other fields together, and the other needs to convert the values in a field from capitalized values to title case values. So if ...
