Trait sp_runtime::traits::IntegerSquareRoot

pub trait IntegerSquareRoot {
    pub fn integer_sqrt_checked(&self) -> Option<Self>;

    pub fn integer_sqrt(&self) -> Self { ... }
}

A trait implementing integer square root.

Required methods

pub fn integer_sqrt_checked(&self) -> Option<Self>

Find the integer square root, returning None if the number is negative (this can never happen for unsigned types).
