# Math function in php

Today, We want to share with you math function in php.In this post we will show you numeric function in php, hear for array functions in php we will give you demo and example for implement.In this post, we will learn about Introduction To Math Class in C# ASP.NET with an example.

And Today, we will discuss – “What are PHP MATH Functions?”

## PHP Math Functions

Contents

As you know PHP is a sever side script language which is used for making the dynamic web pages.

There are various mathematical functions in PHP. PHP Math Function can be used to perform mathematical operations like as a max(), min(), round() or addition, subtraction, division and multiplication and many other mathematical requirements.

This all the functions can handle values within the range of integer as well as float types.

PHP has nice support for mathematical processing.

## PHP Math Functions: Main Tips

• PHP math functions are used for handling float and integer variables.
• These functions are inbuilt into PHP.

Write PHP script to demonstrate math functions.

```";
\$first_no=max(\$first_no,\$n3);
echo "Max is : \$first_no"."";
\$n4=sqrt(\$first_no);
echo "sqrt is  : \$n4"."";
\$first_no=pow(\$second_no,\$n4);
echo "pow is : \$first_no"."";
echo "ceil : ".ceil(\$first_no)."";
echo "floor : ".floor(\$second_no)."";
echo "round : ".round(\$n3.\$first_no)."";
echo "abs : ".abs(\$n4);

?>
```

Following is an explanation of some interesting PHP Math Functions –

### abs () function

It is a Give backs the absolute (positive) value of a number.

```

abs function
';
echo "This abs function User Input is : ".abs (\$num);
?>

```
```"); // 7 (integer)
echo (abs(7).""); //7 (integer)
echo (abs(-7.2).""); //7.2 (float/double)
?>
```

### dechex () function

It is a Converts a decimal number to a hexadecimal number.

```

dechex function
';
echo "This dechex function User Input is : ".dechex (\$num);
?>
}

```

### sqrt() function

It is a Give backs the square root of a number.

```

sqrt  function
';
echo "This sqrt function User Input is : ".sqrt (\$num);
?>

```
```");// 4
echo (sqrt(25)."");// 5
echo (sqrt(7)."");// 2.6457513110646
?>
```

### log() function

It is a Give backs the natural logarithm of a number.

```

log  function
';
echo "This log function User Input is : ".log (\$num);
?>

```

### floor() function

It is a Rounds a number down to the nearest integer.

```

floor  function
';
echo "This floor function User Input is : ".floor (\$num).'';
?>

```
```");// 3
echo (floor(7.333)."");// 7
echo (floor(-4.8)."");// -5
?>
```

### ceil() function

It is a Rounds a number up to the nearest integer.

```

ceil  function
';
echo "This ceil function User Input is : ".ceil (\$num).'';
?>

```
```");// 4
echo (ceil(7.333)."");// 8
echo (ceil(-4.8)."");// -4
?>
```

### pow() function

It is a Give backs x raised to the power of y.

```

pow  function
';
echo "This pow function User Input is : ".pow(2,\$num).'';
echo "This pow function User Input is : ".pow(\$num,2);
?>

```

### max() and min() function

These are Give backs the highest value in an array, or the highest value of several specified values as well as Give backs the lowest value in an array, or the lowest value of several specified values.

```

max and min  function
';
echo "Maximum number  is : ".max (\$num).'';
echo "Minimum number is : ".min (\$num);
?>

```

### sin() function

It is a Give backs the sine of a number.

```

sin()  function
';
echo "Data Content of the sin0 is : ".sin(\$num);
?>

```

### cos() function

It is a Give backs the cosine of a number.

```

cos()  function
';
echo "Data Content of the cos0 is : ".cos(\$num);
?>

```

### tan() function

It is a Give backs the tangent of a number.

```

tan()  function
';
echo "Data Content of the tan45 is : ".tan (\$num);
?>

```
