I am new to Apex and trying to convert Euro to USD and save it in a custom field 'measure'. Here is my code-

CurrencyType conversionRate = [SELECT conversionrate from currencytype where isocode = 'Eur'];
 newProduct.measure__c.= opplineItem.Price / (conversionRate);  

I get the following error

Arithmetic expressions must use numeric arguments.

What is the best way to convert conversionRate to decimal. Is there anything like integer.valueof() to convert to decimal? Thank you

    From what I see in your code, you are trying to divide decimal (opplineItem.Price) by CurrencyType (conversionRate). CurrencyType is not decimal and not numeric either. What you need to do is actually get the conversionrate from CurrencyType variable which is by coincidence also named conversionRate conversionRate.conversionRate. It'd be better if you named the CurrencyType variable differently, something like CurrencyType curType = [SEL...], and then access conversionrate like curType.conversionrate . It'd be clearer

conversionRate (the one with capital R) is a CurrencyType object which is returned by the SOQL.

What you should be doing is :

newProduct.measure__c.= opplineItem.Price / (conversionRate.conversionrate);
