PHP Math Built-in functions

PHP provides a wide range of built-in math functions that allow you to perform various mathematical operations. Here are some of the most commonly used math functions in PHP, along with examples of how to use them:

1. abs(): Returns the absolute value of a number.

   echo abs(-4.2); // 4.2
   

2. sqrt(): Returns the square root of a number.

   echo sqrt(16); // 4
   

3. pow(): Returns the value of a number raised to a specified power.

   echo pow(2, 3); // 8
   

4. exp(): Returns the exponential value of a number.

   echo exp(1); // 2.718281828459
   

5. log(): Returns the natural logarithm of a number.

   echo log(2.718281828459); // 1
   

6. floor(): Returns the next lowest integer value.

   echo floor(4.9); // 4
   

7. ceil(): Returns the next highest integer value.

   echo ceil(4.1); // 5
   

8. round(): Returns the rounded value of a number.

   echo round(4.4); // 4
   echo round(4.6); // 5
   

9. min(): Returns the lowest value in a set of numbers.

   echo min(1, 2, 3); // 1
   

10. max(): Returns the highest value in a set of numbers.

    echo max(1, 2, 3); // 3
    

11. rand(): Generates a random integer between two specified numbers.

    echo rand(1, 10); // 7
    

These are just a few examples of the many math functions available in PHP. By using these functions, you can perform a wide range of mathematical operations in your PHP code.
