+
+The **`Math.Sign()`** method is a static method that returns an integer value indicating the sign of a specified number.
+
+## Syntax
+
+```pseudo
+Math.Sign(number);
+```
+
+**Parameters:**
+
+- `number`: The numeric value for which to determine the sign. Supported types include: `sbyte`, `short`, `int`, `long`, `float`, `double`, and `decimal`.
+
+**Return value:**
+
+Returns an integer value that indicates the sign of the specified number:
+
+- `-1`: if the number is negative
+- `0`: if the number is equal to zero
+- `1`: if the number is positive
+
+## Example: Basic Usage of `Math.Sign()`
+
+In this example, the sign of various numeric values is determined using the `Math.Sign()` method and printed to the console:
+
+```cs
+using System;
+
+public class Example {
+  public static void Main () {
+    // Example numeric values
+    int numInt = -50;
+    float numFloat = 0.0f;
+    double numDouble = 2.7;
+    decimal numDecimal = -0.01m;
+
+    // Determine the sign of each number
+    int numIntSign = Math.Sign(numInt);
+    int numFloatSign = Math.Sign(numFloat);
+    int numDoubleSign = Math.Sign(numDouble);
+    int numDecimalSign = Math.Sign(numDecimal);
+
+    // Print the results
+    Console.WriteLine($"Math.Sign({numInt}) = {numIntSign}");
+    Console.WriteLine($"Math.Sign({numFloat}) = {numFloatSign}");
+    Console.WriteLine($"Math.Sign({numDouble}) = {numDoubleSign}");
+    Console.WriteLine($"Math.Sign({numDecimal}) = {numDecimalSign}");
+  }
+}
+```
+
+This example outputs the following:
+
+```shell
+Math.Sign(-50) = -1
+Math.Sign(0) = 0
+Math.Sign(2.7) = 1
+Math.Sign(-0.01) = -1
+```
+
+## Codebyte Example
+
+In this example, a random number between -100 and 100 is generated, and its sign is determined using the `Math.Sign()` method. A message is printed to indicate whether the random number is negative, positive, or zero:
+
+```codebyte/csharp
+using System;
+
+public class Example {
+  public static void Main () {
+    // Initialize random number generator
+    var randNumGenerator = new Random();
+
+    // Generator random number between -100 and 100
+    int randomNum = randNumGenerator.Next(-100, 100);
+
+    // Determine the sign of randomNum
+    int randomNumSign = Math.Sign(randomNum);
+
+    // Print message based on sign
+    if (randomNumSign == -1) {
+    Console.WriteLine($"Random number, {randomNum}, is negative.");
+    } else if (randomNumSign == 1) {
+    Console.WriteLine($"Random number, {randomNum}, is positive.");
+    } else {
+    Console.WriteLine($"Random number, {randomNum}, is zero.");
+    }
+  }
+}
+```
