Note When subtracting a duration from a value of some type datetime, the resulting value is of that same type. The following expressions are equivalent: The equality operator = is used to determine if two values are equal. #nan is the only value that is not equal to itself. A type value is equal to itself, but may or may not be equal to another type value. Operators are applied to operands to form symbolic expressions. Thanks for being around The expression x produces a list or a table value. relational-expression: A batter with a BABIP of greater than .300 is typically thought of as lucky (though batters with above average speed often have BABIPs greater than .300). optional-projection. Add Ampersand (&) with COUNTIF Function to Count Cells Greater than 0 (Zero) 3. See the examples later in this article. For example, the following expressions are equivalent: The +, -, * and / operators are the arithmetic operators. If x produces a table value and y produces a record value and there are multiple matches for y in x, an error with reason code "Expression.Error" is raised. The only operator that returns results that carry metadata is the meta operator. Heres a set of rules that does what we need: My name is Chris Webb, and I work on the Power BI CAT team at Microsoft.

"<" is less than. If the result is too large for the destination type, z is infinity. What about a slightly more complex but nonetheless common scenario where values greater than 0 are shown as green, values equal to 0 as yellow and values less than 0 as red (with maybe some special handling for blanks too)? You'll find the Conditional Column option in the Add Columns Tab. We all use Excel differently, so it's impossible to write a post that will meet everybody's needs. The result of concatenating two text values is a text value that contains the value of x immediately followed by y. The following holds when evaluating an expression containing conditional logical operators: The conditional logical operators are defined over the types logical and null. The or operator returns true when at least one of its operands is true. unary-expression: I had to flip the "greater than" and "less than" values because in an AND statement that would include everything. I suspect I am going to need to extract the day, month, year data and then go with the #date function but I am not sure. No fields of x other than that named by y is evaluated during the process of field access. If the result is too small for the destination type, z is zero. Assume you need to find the average for marks greater than 90. The following examples illustrate merging records: The following holds when merging two records using x + y: If a field appears in both x and y, the value from y is used.
