PHP Math Functions Complete Reference

The predefined math functions in PHP are used to handle the mathematical operations within the integer and float types. These math functions are part of the PHP core. 

Installation: These functions have not required any installation. The complete list of PHP math functions are given below:

Example: Programs illustrate the decbin() function in PHP:

PHP

<?php
echo decbin(12);
?>

Output:

1100

The complete list of Math Functions are given below:

PHP math Function	Description
abs()	Return the absolute (positive) value of a number.
acos()	Find the arc cosine of a number in radians.
acosh()	Find the inverse hyperbolic cosine of a number passed to it as an argument.
asin()	Find the arc sine of a number in radians.
asinh()	Find the inverse hyperbolic sine of a number passed to it as an argument.
atan2()	Calculate the arc tangent of two variables x and y passed to it as arguments.
atan()	Return tangent of an argument passed to it which has as a numeric value between -Pi/2 and Pi/2 radians.
atanh()	Return tangent of a number passed to it as an argument.
base_convert()	Convert a number given in an arbitrary base to a desired base.
bindec()	Return the decimal equivalent of the binary number
ceil()	This is used to round a number to the nearest greater integer.
cos()	Find the cosine of a number.
cosh()	Find the hyperbolic sine of an angle.
decbin()	Return a string containing a binary representation of the given decimal number argument.
dechex()	Convert a given decimal number to an equivalent hexadecimal number.
decoct()	Return the octal equivalent of a decimal number.
deg2rad()	Convert from degrees to radian, this is where the method deg2rad() comes in aid.
