How do you find the square root of a number in darts?

You can simply use this library by importing it in your code like below :

if x is -Infinity or -0.0 and y is an odd integer, then the result is -pow(-x ,y) . if x is -Infinity or -0.0 and y is not an odd integer, then the result is the same as pow(-x , y) . if y is Infinity and the absolute value of x is less than 1, the result is 0.0. if y is Infinity and x is -1, the result is 1.0.

It can be used when the dart:math package is imported.
