CURRENCY DAX Function (Math and Trig)
Returns the value as a currency data type.
Syntax
| Parameter | Attributes | Description |
|---|---|---|
| Value |
A scalar expression to be converted to currency data type. |
Return values
The value of the expression evaluated and returned as a currency type value.
Remarks
The CURRENCY function rounds up the 5th significant decimal, in value, to return the 4th decimal digit; rounding up occurs if the 5th significant decimal is equal to or larger than 5. For example, if the value is 3.6666666666666 then converting to currency returns $3.6667; however, if the value is 3.0123456789 then converting to currency returns $3.0123.
If the data type of the expression is Boolean then CURRENCY() will return $1.0000 for True values and $0.0000 for False values.
If the data type of the expression is String then CURRENCY() will try to convert string to a number; if the conversion succeeds the number will be converted to currency, otherwise, an error is returned.
If the data type of the expression is DateTime then CURRENCY() will convert the DateTime value to a number and that number to currency. DateTime values have an integer part that represents the number of days between the given date and 1900-03-01 and a fraction that represents the fraction of a day (where 12 hours or noon is 0.5 day). If the value of the expression is not a proper DateTime value, an error is returned.
The CURRENCY() function has the same behavior as calling CONVERT with a CURRENCY argument. The two following statements are equivalent:
CURRENCY ( <expression> ) CONVERT ( <expression>, CURRENCY )

Examples
-- CURRENCY converts any expression in a CURRENCY datatype
-- The Currency data type is called Fixed Decimal Number in Power BI
-- This data type stores 4 digits after the decimal point
