Daily DAX : Day 392 DEGREES

Power BI DAX: DEGREES Function

Syntax

DEGREES(angle_in_radians)

Description

The DEGREES function converts a number representing an angle in radians to degrees.

This is useful when working with trigonometric functions in DAX (like SIN, COS, TAN), which expect or return values in radians, but you need results in degrees for reporting or calculations.

Parameters

Parameter Description
angle_in_radians A real number representing an angle in radians.

Return Value

A decimal number representing the angle in degrees.

Example 1: Basic Conversion

Convert π radians to degrees:

Degrees in DAX = DEGREES(PI())

Result: 180

Example 2: With Trigonometric Function

Calculate sine of 30° by converting to radians first:

Sine of 30° = SIN(DEGREES(30) * PI() / 180)

But to go the other way (radians → degrees):

Angle in Degrees = DEGREES(ASIN(0.5))

Result: 30

Use Cases

  • Converting results from ASIN, ACOS, or ATAN (which return radians) into degrees for display.
  • Working with geographic data where bearing or direction is calculated in radians but reported in degrees.
  • Creating custom trigonometric calculations in reports where users expect degree-based input/output.

Related Functions

  • RADIANS(angle_in_degrees) – Opposite of DEGREES
  • PI() – Returns the value of π
  • SIN(), COS(), TAN() – Trigonometric functions (use radians)

Daily DAX : Day 131 SELECTEDMEASURE

 The SELECTEDMEASURE function in Power BI's DAX (Data Analysis Expressions) language is a powerful tool used primarily within calculation groups to dynamically reference the measure currently being evaluated in a report. It’s part of the calculation group feature introduced to streamline complex reporting scenarios and improve maintainability by reducing the need to duplicate measure logic. What is SELECTEDMEASURE? SELECTEDMEASURE is a DAX function that returns a reference to the measure that is currently active or "selected" in the context of a calculation group. It doesn’t take any arguments and is typically used in the expression of a calculation item within a calculation group. This allows you to write generic logic that can dynamically apply to whichever measure is being evaluated in a visual, without hardcoding specific measure names. Syntax SELECTEDMEASURE()     Returns: A reference to the measure currently being evaluated in the report context. Use Case SELECTEDME...

Daily DAX : Day 446 INFO.CSDLMETADATA

Power BI DAX Function: INFO.CSDLMETADATA INFO.CSDLMETADATA` is a specialized DAX function introduced as part of a broader set of "INFO" functions (like `INFO.TABLES` or `INFO.MEASURES`) used for **model introspection**. It allows you to programmatically access the underlying structure of your Power BI semantic model. What does it do? The function returns a table with a single column containing the Conceptual Schema Definition Language (CSDL)  metadata of your model in XML format . In plain English, it exports a highly technical "blueprint" of your entire data model—including tables, columns, relationships, and measures—as a structured XML string. It is essentially the DAX equivalent of the `DISCOVER_CSDL_METADATA` Dynamic Management View (DMV) used in Analysis Services. --- Syntax and Output The syntax is straightforward as it requires no arguments: ```dax EVALUATE INFO.CSDLMETADATA() ``` Return Value : A table with one column and one row. Content : A long string ...

Daily DAX : Day 453 ENDOFWEEK

Power BI DAX Function: ENDOFWEEK Description The ENDOFWEEK function is a Time Intelligence function in DAX (Data Analysis Expressions) used in Power BI. It returns the date that represents the end of the week containing a specified date (typically Saturday, as weeks are considered to start on Sunday by default in DAX time intelligence). Syntax ENDOFWEEK( [, ]) : A column reference (usually from a Date table) or a date expression. Required. : Optional. Specifies the week-ending convention. Default is Saturday if omitted. Examples 1. Basic usage (default: week ends on Saturday): End of Week = ENDOFWEEK('Date'[Date]) For a date like January 8, 2026 (Thursday), this would return January 10, 2026 (Saturday). 2. In a measure for cumulative sales up to end of week: Total Sales to End of Week = CALCULATE( SUM(Sales[Amount]), DATESBETWEEN('Date'[Date], ST...
