How does the CURRENCY function (DAX) work?
The CURRENCY function (DAX) converts a decimal number into a generic currency value by effectively adding a generic currency symbol (¤), a decimal point, and one comma for every three digits preceding the decimal.
CURRENCY Formula Syntax
How do you use the CURRENCY function?
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 or larger than 5. For example, if value is 3.6666666666666 then converting to currency returns $3.6667; however, if value is 3.0123456789 then converting to currency returns $3.0123.

Considerations when using the CURRENCY function
- If the data type of the expression is TrueFalse then CURRENCY( <TrueFalse>) will return $1.0000 for True values and $0.0000 for False values.
- If the data type of the expression is Text then CURRENCY(<Text>) will try to convert text 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(<DateTime>) 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 days). If the value of the expression is not a proper DateTime value an error is returned.
