Absolute value of a decimal

Dear all In a rule I would like to compare to absolute values of decimals. Code looks like that: if (Math.abs((AF.state as DecimalType) - (Temp_mittel as DecimalType)) > Math.abs((AF.state as DecimalType) - (Aussentemp_H as DecimalType))) Aussentemp_H.sendCommand(AF.state as DecimalType) end However I realized that Math.abs(..) only works for integers. What is the right method for decimals, and is my code above correct? Any help would be highly appreciated. Best regards Rolf

but not eit drives you to primitives again for abs().

It might be more effecient to write your own if-then abs comparison for Numbers
