PHP Math Functions | With Examples

PHP math functions with examples. As we know PHP stands for Hypertext Preprocessor. PHP is a programming language that could be used to create small and vast applications like simple forms etc to large-scale business applications. PHP is a server-side based scripting language. All programming language has numbers of in-built default capabilities.

These capabilities assist the programmer to immediately compose the needed program. These inbuilt functionalities hold logics inside which is needed as per our specification. These inbuilt capabilities may be on string-based, array-based, number-based, JSON based capabilities, etc

Now let us take a look what is PHP Math Functions

PHP Math Functions

Math functions are inbuilt capabilities of PHP as a programming language. The primary role of these PHP functions is to give a mechanism in which a programmer can do amazing sorts of math calculations or similar principles. These give a swift hands-on for development without writing a long part of the program.

Now we will try to explain various PHP math functions, onward with its use an Example:

asin() function : It was founded in PHP version 4+. It requires an argument in the range of -1 to +1. If a number out of a specified range is passed in an argument then it returns NaN unless it returns the arc sine value of the number. The return type of the function is the arc sine of a number.

<?php
echo(asin(0.25) . "<br>");
echo(asin(-0.25) . "<br>");
echo(asin(4) . "<br>");
echo(asin(0.7153));
?>
Output
0.25268025514208
-0.25268025514208
NAN
0.79705330887752

acos() function : It was founded in PHP 4+ version. It requires an argument in the range of -1 to +1. If a number out of a specified range is passed in an argument then it returns NaN unless it returns the arc cosine value of the number. The return type of the function is arc cosine of a number.

<?php
echo(acos(0.25) . "<br>");
echo(acos(-0.25) . "<br>");
echo(acos(4) . "<br>");
echo(acos(0.7153));
?>
Output
1.3181160716528
1.823476581937
NAN
0.77374301791738

ceil() function : It was founded in PHP 4+ version. It forms a number up to the most adjacent integer. For instance, the ceil of 0.25 will give 1. It returns the total number in the form of the nearest integer which is more inclusive than the given argument

<?php
echo(ceil(0.25) . "<br>");
echo(ceil(-0.25) . "<br>");
echo(ceil(4) . "<br>");
echo(ceil(0.7153));
?>
Output
1
-0
4
1

floor() function : It was founded in PHP 4+ version. It forms a number under the most adjacent integer. For instance, the floor of 0.25 will give 0. It returns the whole number in the form of the nearest integer which is less than the passed argument

<?php
echo(floor(0.25) . "<br>");
echo(floor(-0.25) . "<br>");
echo(floor(4) . "<br>");
echo(floor(0.7153));
?>
Output
0
-1
4
0

pi() function : It was founded in PHP 4+ version. It returns the value of a PI and its return type is a float.

<?php
echo(pi() . "<br>");
?>
Output
3.1415926535898

pow() PHP Math functions : It was founded in PHP 4+ version. It holds two disputes say x and y. It calculates x raised to the power of y. its return type is integer or float which depends upon the quality of the argument

<?php
echo(pow(4,2) . "<br>");
echo(pow(3,4) . "<br>");
echo(pow(6,2) . "<br>");
echo(pow(7,3));
?>
Output
16
81
36
343

log() function : It was founded in PHP 4+ version. It takes two arguments say x and y where x is a number and y is the logarithm of a number to support. If y is not passed then the default value ‘e’ is allowed. Its return type is float.

<?php
echo(log(3.718) . "<br>");
echo(log(3) . "<br>");
echo(log(2) . "<br>");
echo(log(1));
?>
Output
1.3131858892993
1.0986122886681
0.69314718055995
0

Conclusion

PHP is a really broad programming language, we can read and learn it in order to make web applications. It is done to manage server-side scripting logic. Although we could enter our HTML code also within PHP as we have used in example parts.
PHP has a general database for inbuilt capabilities. There are certain functionalities that use string as a parameter, other capabilities use an array. These inbuilt capabilities assist us to explain our specifications without composing much code for a program.
