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
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.
<?php $first_no=500; $second_no=250; $n3=min($first_no,$second_no); echo "Min is : $n3"."<br><br>"; $first_no=max($first_no,$n3); echo "Max is : $first_no"."<br><br>"; $n4=sqrt($first_no); echo "sqrt is : $n4"."<br><br>"; $first_no=pow($second_no,$n4); echo "pow is : $first_no"."<br><br>"; echo "ceil : ".ceil($first_no)."<br><br>"; echo "floor : ".floor($second_no)."<br><br>"; echo "round : ".round($n3.$first_no)."<br><br>"; echo "abs : ".abs($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.
<html> <body style="background-color:grey;"> <h3>abs function</h3> <?php $num=-10; echo "User Input number is : $num".'<br>'; echo "This abs function User Input is : ".abs ($num); ?> </body> </html>
<?php echo (abs(-7)."<br/>"); // 7 (integer) echo (abs(7)."<br/>"); //7 (integer) echo (abs(-7.2)."<br/>"); //7.2 (float/double) ?>
dechex () function
It is a Converts a decimal number to a hexadecimal number.
<html> <body style="background-color:grey;"> <h3>dechex function</h3> <?php $num=525; echo "User Input number is : $num".'<br>'; echo "This dechex function User Input is : ".dechex ($num); ?> </body>} </html>
sqrt() function
It is a Give backs the square root of a number.
<html> <body style="background-color:grey;"> <h3>sqrt function</h3> <?php $num=625; echo "User Input number is : $num".'<br>'; echo "This sqrt function User Input is : ".sqrt ($num); ?> </body> </html>
<?php echo (sqrt(16)."<br/>");// 4 echo (sqrt(25)."<br/>");// 5 echo (sqrt(7)."<br/>");// 2.6457513110646 ?>
log() function
It is a Give backs the natural logarithm of a number.
<html> <body style="background-color:grey;"> <h3>log function</h3> <?php $num=10; echo "User Input number is : $num".'<br>'; echo "This log function User Input is : ".log ($num); ?> </body> </html>
floor() function
It is a Rounds a number down to the nearest integer.
<html> <body style="background-color:grey;"> <h3>floor function</h3> <?php $num=5.89; echo "User Input number is : $num".'<br>'; echo "This floor function User Input is : ".floor ($num).'<br>'; ?> </body> </html>
<?php echo (floor(3.3)."<br/>");// 3 echo (floor(7.333)."<br/>");// 7 echo (floor(-4.8)."<br/>");// -5 ?>
ceil() function
It is a Rounds a number up to the nearest integer.
<html> <body style="background-color:grey;"> <h3>ceil function</h3> <?php $num=5.89; echo "User Input number is : $num".'<br>'; echo "This ceil function User Input is : ".ceil ($num).'<br>'; ?> </body> </html>
<?php echo (ceil(3.3)."<br/>");// 4 echo (ceil(7.333)."<br/>");// 8 echo (ceil(-4.8)."<br/>");// -4 ?>
pow() function
It is a Give backs x raised to the power of y.
<html> <body style="background-color:grey;"> <h3>pow function</h3> <?php $num=5; echo "User Input number is : $num".'<br>'; echo "This pow function User Input is : ".pow(2,$num).'<br>'; echo "This pow function User Input is : ".pow($num,2); ?> </body> </html>
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.
<html> <body style="background-color:grey;"> <h3>max and min function</h3> <?php $num=array(2,6,10,3,15); Echo "User Input number are :" ." ". $num[0].",".$num[1].",".$num[2].",".$num[3].",".$num[4].'<br>'; echo "Maximum number is : ".max ($num).'<br>'; echo "Minimum number is : ".min ($num); ?> </body> </html>
sin() function
It is a Give backs the sine of a number.
<html> <body style="background-color:grey;"> <h3>sin() function</h3> <?php $num=0; Echo "Data Content of the angle : $num".'<br>'; echo "Data Content of the sin0 is : ".sin($num); ?> </body> </html>
cos() function
It is a Give backs the cosine of a number.
<html> <body style="background-color:grey;"> <h3>cos() function</h3> <?php $num=0; Echo "Data Content of the angle : $num".'<br>'; echo "Data Content of the cos0 is : ".cos($num); ?> </body> </html>
