Trait polkadot_sdk_frame::arithmetic::traits::CheckedDiv

pub trait CheckedDiv: Sized + Div<Output = Self> {
    // Required method
    fn checked_div(&self, v: &Self) -> Option<Self>;
}

Performs division that returns None instead of panicking on division by zero and instead of wrapping around on underflow and overflow.

Required Methods

fn checked_div(&self, v: &Self) -> Option<Self>

Divides two numbers, checking for underflow, overflow and division by zero. If any of that happens, None is returned.

Object Safety

This trait is not object safe.
