Hi All,

I am struggling to return the value of a field as a two decimal place field i.e. currency fields back to my VF page.

Here is my class:
 

public class ESDCDA {
    
    private final Opportunity opp;
    public ESDCDA(ApexPages.StandardController stdController) {
        this.opp = (Opportunity)stdController.getRecord();
        
    }
    
    double eop; double op;
    
    
    list<AggregateResult>  aK;
    transient public double total {get; set;} 
    transient public decimal oppr {get; set;}
    transient public decimal losm {get; set;}
    transient public decimal mc {get; set;}  
    transient public decimal dcc {get; set;}
    transient public decimal ssp {get; set;}
    transient public decimal ans {get; set;}
    
    
    public void showlist(){
        
        aK=[select mpan__c, 
            siteaddress__c,
            Site_Contact__c,
            Site_Telephone_Number__c,
            Sub_Product__c,
            sum(on_supply_service_charge__c)ossc,
            InvoiceAddress__c
            from es_mpan__c
            where opportunity_name__c =:opp.id 
            group by mpan__c, 
            siteaddress__c,
            Site_Contact__c,
            Site_Telephone_Number__c,
            Sub_Product__c,
            InvoiceAddress__c]; 
        
        if(opp.ES_Opportunity_2__c != Null){
            
            aggregateResult[]aK1 = [select mpan__c, 
                                    siteaddress__c,
                                    Site_Contact__c,
                                    Site_Telephone_Number__c,
                                    Sub_Product__c,
                                    InvoiceAddress__c,
                                    sum(on_supply_service_charge__c)ossc
                                    from es_mpan__c 
                                    where opportunity_name__c = :opp.ES_Opportunity_2__c 
                                    group by mpan__c, 
                                    siteaddress__c,
                                    Site_Contact__c,
                                    Site_Telephone_Number__c,
                                    Sub_Product__c,
                                    InvoiceAddress__c];
            ak.addAll(ak1);
            
            AggregateResult[] t = [select sum(Total_Annual_Charges__c)tc, 
                                   sum(es_opportunity_2__r.Total_Annual_Charges__c)etc 
                                   from opportunity 
                                   where id =:opp.id];
            
            if(double.valueof(t[0].get('tc')) == Null){op = 0.00;}else{op = double.valueof(t[0].get('tc'));}
            if(double.valueof(t[0].get('etc')) == Null){eop = 0.00;}else{eop = double.valueof(t[0].get('etc'));}
            
            total = op + eop;
        }else{
            
            AggregateResult[] t = [select sum(Total_Annual_Charges__c)tc                               	 	  
                                   from opportunity 
                                   where id =:opp.id];
            
            op = double.valueof(t[0].get('tc'));
            total = op;
            
            AggregateResult[] sm = [select
                                    sum(Outright_Purchase_Price__c)oppr,
                                    sum(Lease_of_Secondary_Metering__c)losm,
                                    sum(Maintenance_Charge__c)mc,
                                    sum(Data_Collection_Charge__c)dcc,
                                    sum(Supply_Software_Package__c)ssp,
                                    sum(Ancillary_Services__c)ans
                                    from es_mpan__c
                                    where opportunity_name__c =:opp.id];
            
            oppr = decimal.valueof(sm[0].get('oppr'));
            losm = decimal.valueof(sm[0].get('losm'));
            mc = decimal.valueof(sm[0].get('mc'));
            dcc = decimal.valueof(sm[0].get('dcc'));
            ssp = decimal.valueof(sm[0].get('ssp'));
            ans = decimal.valueof(sm[0].get('ans'));
        }
    }
    
    public list<AggregateResult> jalist{
        get { return aK;}
    }
    
}

If I use double I only get one decimal place unless the field was entered with two i.e. 10.25 will return 10.25 but 10 return 10.0

With decimal I get the error: Variable does not exist: decimal at line 87

Any help is appreciated.

Thanks
