Lsit of decimal

List<Decimal> cal =new List<Decimal>();
public decimal fun(){
cal.add(0.0);
cal.add(0.1);
return cal;  // This is possible, But when I have to return that time to display error: "Return value must be of type: Decimal at line"
}

If any one know how to return the list decimal value into function.

Hi Vadivel, 

Since your method returning just Decimal, NOT List<Decimal>. Based on you need you can alter the below suggested codes,
  
List<Decimal> cal =new List<Decimal>();
public decimal fun(){
cal.add(0.0);
cal.add(0.1);
return cal[0]; // Here you can return any one of decimal value by referring list   
index.
}
OR Change your method to return type from Decimal to List<Decimal> 
List<Decimal> cal =new List<Decimal>();
public List<decimal> fun(){
cal.add(0.0);
cal.add(0.1);
return cal; 
}

@Vadivel -

You can try this: 
List<Decimal> cal =new List<Decimal>(); // if cal is an instance variable
public List<Decimal> fun(){
    cal.add(0.0);
    cal.add(0.1);
    return cal;  
}
OR 
public List<Decimal> fun(){
    List<Decimal> cal =new List<Decimal>();
    cal.add(0.0);
    cal.add(0.1);
    return cal;  
}
OR 
List<Decimal> cal =new List<Decimal>(); // if cal is an instance variable
public void fun(){
    cal.add(0.0);
    cal.add(0.1);
}

Hope this will be resolve the issue.

Please mark it as the best answer if it helps.

Thanks

This is my code.

In your secod method you are returning decimal instead of list. I have updated your code, please try the below code, let me know if you still face issue.
  
List<Decimal> salePrice = new List<Decimal>();
private List<Decimal> scenario4(Id ssVar1Id){
        if(mapServiceSheetIdVisitRecord.get(ssVar1Id).Priority__c == '4 Hour Corrective'){
            if(!isOutOfMonFri830AMto5PM){
                System.debug('####'+'Sce 4: Pri=4C,Dep Time : Inside Office Hours');
                insideOfficeHoursPri4CSce4(ssVar1Id); 
            }
return salePrice; 
}

private List<Decimal> insideOfficeHoursPri4CSce4(Id ssVar1id){
        System.debug('####'+'Sce 4: Pri=4C,Dep Time : Inside Office Hours:BEGIN');
        System.Debug('####List Of Split Hours is'+listOfSplitHoursSpent);
        If(listOfSplitHoursSpent.size() > 1){
        noOfHoursInOfficeTime=listOfSplitHoursSpent.get(0);
        noOfHoursOutOfficeTime = listOfSplitHoursSpent.get(1);
        noOfHoursInOfficeTimeAgain = listOfSplitHoursSpent.get(2);}
        callOutCharge4HourResponse = (mapServiceSheetIdSiteContractRecord.get(ssVar1id)).X4_Hour_Reactive_Call_Out_Charge__c;
        labourChargePerHour=(mapServiceSheetIdSiteContractRecord.get(ssVar1id)).Labour_Charge__c;
        if(callOutCharge4HourResponse==null){
            System.debug('####callOutCharge4HourResponse is Null, Hence Substituted by 0');
            callOutCharge4HourResponse=0.0;
        }
        if(labourChargePerHour==null){
            System.debug('####labourChargePerHour is Null, Hence Substituted by 0');
            labourChargePerHour=0.0;
        }
        salePrice1 = callOutCharge4HourResponse +(labourChargePerHour*noOfHoursInOfficeTime);
        Calloutcharge = callOutCharge4HourResponse;
        Labourcharge = labourChargePerHour*noOfHoursInOfficeTime;
        salePrice.add(salePrice1);
        salePrice.add(Calloutcharge);
        salePrice.add(Labourcharge);
        System.debug('####'+'Sce 4: Pri=4C,Dep Time : Inside Office Hours:END');
        System.debug('####'+'Sce 4: Pri=4C,Dep Time : Inside Office Hours:SALEPRICE'+salePrice);
        return salePrice;
    }
