Creating formula field
What is a formula field? It is a read
only field, the value of formula filed evaluate from expression defined
by us. If we update any value in the expression, it automatically
updates formula field value. We can create formula fields in both
standard and custom object.
We can return formule result in 7 ways those are:
1. Checkbox: Calculate a boolean value
2. Currency: Calculate a dollar or other currency amount and automatically format the field as a currency amount.
3. Date: Calculate a date, for example, by adding or subtracting days to other dates.
4. Date/Time: Calculate a date/time, for example, by adding a number of hours or days to another date/time.
5. Number: Calculate a numeric value.
6. Percent: Calculate a percent and automatically add the percent sign to the number.
7. Text: Create a text string, for example, by concatenating other text fields.

Creating this type of filed is
like creating a normal salesforce field with type formula and we need to
select result typed & provide expression.
