Formula fields are used to calculate different types of values, including numeric values, text values, date values, etc. Formula fields and their resulting return value have certain data types associated with them and there are specific operators that can be used for each data type. It is necessary to understand the type of fields required for creating formula fields and the compatibility between the data types and the operators. For instance, the operator " * " (for multiplication) is used on numeric values and not on text values.
The following table helps you to understand the type of arguments required for numeric functions along with the type of syntax that needs to be formed.

To create String type formula fields
The following table helps you to understand the type of arguments required for DateTime functions along with the type of syntax that needs to be formed.
Function | Description | Usage | Examples |
Newdate | Creates a date from the year, month, day and time. | Newdate(year,month,day, hour,minute,'string') | Newdate(2007,12,21,06,30,'AM') returns quot;21/12/2007 06:30 AM"1 |
