In Groovy, you can get the square root of a number using the Math.sqrt() method.
Here's an example of how to get the square root of a number:
`` groovy
def num = 16
def sqrtNum = Math.sqrt(num)
println "Square root of $num is $sqrtNum"
This will output:
Square root of 16 is 4.0
You can also directly get the square root of a number without assigning it to a variable:
println Math.sqrt(25)
This will output:
5.0
