sourcepub fn modpow(&self, exponent: &Self, modulus: &Self) -> Self
pub fn modpow(&self, exponent: &Self, modulus: &Self) -> Self
Returns (self ^ exponent) mod modulus
Note that this rounds like mod_floor, not like the % operator,
which makes a difference when given a negative self or modulus.
The result will be in the interval [0, modulus) for modulus > 0,
or in the interval (modulus, 0] for modulus < 0
Panics if the exponent is negative or the modulus is zero.
sourcepub fn sqrt(&self) -> Self
pub fn sqrt(&self) -> Self
Returns the truncated principal square root of self –
see Roots::sqrt.
sourcepub fn cbrt(&self) -> Self

see Roots::cbrt.
sourcepub fn nth_root(&self, n: u32) -> Self
pub fn nth_root(&self, n: u32) -> Self
Returns the truncated principal nth root of self –
See Roots::nth_root.
sourcepub fn trailing_zeros(&self) -> Option<u64>
pub fn trailing_zeros(&self) -> Option<u64>
Returns the number of least-significant bits that are zero,
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
sourcepub fn set_bit(&mut self, bit: u64, value: bool)
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

or negative inifinity, otherwise None is returned if the value cannot
be represented by an f64. Read moresourcefn to_isize(&self) -> Option<isize>
fn to_isize(&self) -> Option<isize>
Converts the value of
self to an isize. If the value cannot be
represented by an isize, then None is returned. Read moresourcefn to_i8(&self) -> Option<i8>
fn to_i8(&self) -> Option<i8>
Converts the value of
self to an i8. If the value cannot be
represented by an i8, then None is returned. Read moresourcefn to_i16(&self) -> Option<i16>
fn to_i16(&self) -> Option<i16>
Converts the value of
self to an i16. If the value cannot be
represented by an i16, then None is returned. Read moresourcefn to_i32(&self) -> Option<i32>
fn to_i32(&self) -> Option<i32>
Converts the value of
self to an i32. If the value cannot be
represented by an i32, then None is returned. Read moresourcefn to_usize(&self) -> Option<usize>
fn to_usize(&self) -> Option<usize>
Converts the value of
self to a usize. If the value cannot be
represented by a usize, then None is returned. Read moresourcefn to_u8(&self) -> Option<u8>
fn to_u8(&self) -> Option<u8>
Converts the value of
self to a u8. If the value cannot be
represented by a u8, then None is returned. Read moresourceimpl TryFrom<&BigInt> for BigUint
