# perl math functions

Perl provides a number of built-in math functions that allow you to perform various mathematical operations. These functions can be used to perform calculations, manipulate numbers, and solve mathematical problems. Here are some commonly used math functions in Perl:

**abs()**: This function returns the absolute value of a number. For example,`abs(-5)`

returns 5.**sqrt()**: The`sqrt()`

function calculates the square root of a number. For instance,`sqrt(16)`

returns 4.**exp()**: The`exp()`

function returns the value of Euler's number (approximately 2.71828) raised to the power of a given number. For example,`exp(1)`

returns Euler's number (approximately 2.71828).**log()**: The`log()`

function calculates the natural logarithm of a number. For instance,`log(10)`

returns 2.30259.**sin()**,**cos()**, and**tan()**: These functions calculate the trigonometric sine, cosine, and tangent of a given angle, respectively. For example,`sin(0)`

returns 0,`cos(0)`

returns 1, and`tan(0)`

returns 0.**int()**: The`int()`

function returns the integer part of a number. For instance,`int(3.14)`

returns 3.**rand()**: The`rand()`

function generates a random number between 0 and 1. For example,`rand()`

may return 0.34567.

These are just a few examples of the math functions available in Perl. You can find more information and additional math functions in the Perl documentation.
