HI Michael,
Greetings!!

The decimal class in the apex has the method called setscale() it is used to set the decimal value to the specific number or places.
Here is the example. 
Decimal myValue= 8.8432108523;
Decimal setScaledValue = myDecimal.setscale(2);
the value will now become the '8.84'.
You can also Round-Up the values as per the need.
Here is the link for all the methods of the decimal class.
