Square root functionality in rust

Which libraries are needed to be imported for implementing square root functionality in rust, provided that the user gives the input value for both integer and float?

F32 and F64 sqrt is available from STD
https://doc.rust-lang.org/std/primitive.f64.html#method.sqrt

num_integer::Roots implements it for integers – https://docs.rs/num-integer/0.1.41/num_integer/trait.Roots.html#method.sqrt
