 ====== Sqr ======
-Returns the square root of a value.
+The **Sqr** function returns the square root ($\sqrt{x}$) of a numeric value. It is essential for distance calculations, sensor data normalization, and power computations.
+For the best precision, use the ''Single'' data type. **Note:** Input must be a **non-negative** number; negative values will cause a runtime error.
+Example
 <code xbasic>
-A=Sqr B   ' Return the square root of B
+Dim A As Single
+Dim B As Single
+B = 25.0
+A = Sqr(B)      ' Returns 5.0
 </code>
+==== Explanation: ====
+  * **B**: A non-negative number.
+  * **Sqr B**: Calculates the square root.
+  * **A**: Stores the result.
+**Usage Tip (Distance):**
+To find the distance between two points $(x1, y1)$ and $(x2, y2)$:
+''Distance = Sqr((x2-x1)^2 + (y2-y1)^2)''
