Calculating the square root of the value

To calculate the square root of the value, call the sqrt method on it:

say 9.sqrt; # 3

The routine is also defined in Perl 6 as a standalone built-in function. Consider the following code snippet:

say sqrt(9); # 3

As the sqrt method is inherited from the Numeric role, the result is a floating-point value:

say 10.sqrt; # 3.16227766016838
