Trait sp_runtime::traits::IntegerSquareRoot
pub trait IntegerSquareRoot {
// Required method
fn integer_sqrt_checked(&self) -> Option<Self>
where Self: Sized;
// Provided method
fn integer_sqrt(&self) -> Self

}Expand description
A trait implementing integer square root.
Required Methods§
fn integer_sqrt_checked(&self) -> Option<Self>where
Self: Sized,
fn integer_sqrt_checked(&self) -> Option<Self>where Self: Sized,
Find the integer square root, returning None if the number is negative (this can never
happen for unsigned types).
Provided Methods§
fn integer_sqrt(&self) -> Selfwhere
Self: Sized,
fn integer_sqrt(&self) -> Selfwhere Self: Sized,
Find the integer square root.
See Integer_square_root on wikipedia for more information (and also the source of this algorithm)
Panics
For negative numbers (i family) this function will panic on negative input
