What is the currency field type?

I am confused with the field type of currency field. In Apex developer guide it is mentioned as "Currency fields are automatically assigned the type Decimal."(https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/langCon_apex_primitives.htm#d165227e151).
And  in soap developer guide as  type double.(https://developer.salesforce.com/docs/atlas.en-us.api.meta/api/field_types.htm#i1435541).

Anyone please provide clarification

Hi sumat srivastav 6,

Please find the detailed explanation of your query :

First, you need to understand the difference between decimal and double.

Decimal: A number that includes a decimal point. Decimal is an arbitrary precision number. Currency fields are automatically assigned the type Decimal.
ex: Decimal dec = 19.23;

Double: A 64-bit number that includes a decimal point. Doubles have a minimum value of -263 and a maximum value of 263-1.
ex: Double  d = 3.14159;

The fundamental difference is that the double is a base 2 fraction, whereas a decimal is a base 10 fraction.

double stores the number 0.5 as 0.1, 1 as 1.0, 1.25 as 1.01, 1.875 as 1.111, etc.
decimal stores 0.1 as 0.1, 0.2 as 0.2, etc.

With respective to currency fields decimal and double both can be used but the difference is The scale (number of digits to the right of decimal point) can be set for a Decimal, but cannot for a Double. This is important for currency and other calculations (division). Doubles do not have this option. You'll find that Doubles have a limited number of methods available to them compared to Decimals. Unless you know that you're dealing with very large numbers requiring a high degree of precision, Decimals will generally be a better choice.

Please mark my solution  as best answer if this helps you .........................

Best Regards

You are correct. The field type of currency field in Salesforce is Decimal in Apex and double in SOAP.
The reason for this is that Apex is a compiled language, while SOAP is an interpreted language. Compiled languages require that all data types be explicitly declared, while interpreted languages can infer the data type from the context.
In Apex, the Decimal data type is used for currency fields because it can store a precise number of decimal places. The double data type in SOAP is also a floating-point number, but it can only store a limited number of decimal places.

For most purposes, the difference between the two data types is not significant. However, if you need to store a very precise number of decimal places, you should use the Decimal data type in Apex.

The Apex developer guide is correct in stating that currency fields are automatically assigned the type Decimal. This is because the Salesforce platform stores currency values as decimals. However, the SOAP developer guide is also correct in stating that the type of a currency field is double. This is because the SOAP API represents currency values as doubles.
The reason for this difference is that the Salesforce platform and the SOAP API use different data types to represent numbers. The Salesforce platform uses the Decimal data type, which is a high-precision data type that is optimized for storing currency values. The SOAP API uses the double data type, which is a more general data type that can represent a wide range of numbers.
When you retrieve a currency value from the Salesforce platform, it will be returned to you as a Decimal value. When you create or update a currency value using the SOAP API, you must provide the value as a double.
Here is a table that summarizes the differences between the Decimal and double data types:
| Data type | Description | |---|---|---| | Decimal | A high-precision data type that is optimized for storing currency values. | | double | A more general data type that can represent a wide range of numbers. |
When working with currency fields in Salesforce, it is important to be aware of the differences between the Decimal and double data types. This will help you to avoid errors when retrieving and updating currency values.
In general, I would recommend using the Decimal data type when working with currency values in Salesforce. This is because the Decimal data type is more precise and is optimized for storing currency values. However, if you are working with the SOAP API, you must use the double data type to represent currency values. by https://www.ufabetwins.ai/
