–
see Roots::cbrt.

or None
if the entire number is zero.
sourcepub fn bit(&self, bit: u64) -> bool
pub fn bit(&self, bit: u64) -> bool
Returns whether the bit in position bit
is set,
using the two’s complement for negative numbers

pub fn set_bit(&mut self, bit: u64, value: bool)
Sets or clears the bit in the given position, using the two’s complement for negative numbers
Note that setting/clearing a bit (for positive/negative numbers, respectively) greater than the current bit length, a reallocation may be needed to store the new digits
