Perl | sqrt() Function

Many times it happens that while solving mathematical expressions we require to calculate the square root of a number. To solve this issue, like other programming language Perl provides us with a built-in function sqrt() which can be used to calculate the square root of a number.

Syntax: sqrt value Returns: square root of the value passed

Note: sqrt() can only calculate square root of positive values.   Example 1: Perl

#!/usr/bin/perl

# Calculating square root using sqrt()
$square_root = sqrt(64);

# Printing the result
print "Squareroot of 64 is: $square_root";

Example 2: Perl

#!/usr/bin/perl

# Calculating square root using sqrt()
$square_root = sqrt(16);

# Printing the result
print "Squareroot of 16 is: $square_root";
