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:
$square_root = sqrt (64);
print "Squareroot of 64 is: $square_root" ;
|
Output:
Squareroot of 64 is: 8
Example 2:
$square_root = sqrt (16);
print "Squareroot of 16 is: $square_root" ;
|
Output:
Squareroot of 16 is: 4
